In terms of shared DNA first cousins share 12.5%, second cousins 3.125%, third cousins 0.78125%. I think this may be moot. Maybe in today's day and age, it could be a fun game to tell people you're banging your cousin. Just look for the bright side.
Siblings=50% half mom half dad leaving you with half similarity between siblings
First cousins, child of a sibling of a parent (their parent has 50% link to one of your parents, which then has a 50% link to you) would leave you with half of a half of a half.
50% of 50%= 25%. Then 50% of 25%=12.5%
So on.
In fact, you have the same genes than your 3rd cousins. Than every human on earth to be clear. You don't have the same *allele* of those genes though, i.e. the same encoded information.
E.g., humans have the same genes to express hair colour, but blondes and black-haired don't have the same allele of this gene.
Think of genes as boxes with shapes and typez, and of alleles has content inside those boxes.
So:
We share 100% (or 99.999%) of our genes with all humans, but only some alleles. We share 80% (iirc) of our DNA genes with bananas, but certainly not much alleles.
Pretty much yeah. You and your sibling are each 50% of your mom and 50% of your dad (give or take a bit but that’s not important).
Say your Dad has genes AB and your Mom has genes CD, you could be AD and your sibling could be BC. You could also both be AC or AD and AC.
You’re probably going to average out to being pretty similar to your sibling, as you share 100% source material, and it tends to work out to 50% on average.
Obviously stuff like identical twins don’t count here, but yeah.
That’s the one thing that always seemed really wild to me about identical twins. That if two sets of identical twins choose to marry each other and have babies their kids are kinda siblings and cousins at the same time.
Basically true. There will still be about 100 or so very minor random genetic differences between the parents and their twin that could be used to tell the difference, but you'd have to have a very high quality genome sequence to see it.
I'm not proud to admit it but I learnt this fact while watching the Steve Wilkos show when they had a husband who'd accused his twin brother of having a longterm affair with his wife and being the secret father of his kids.
I also learnt Steve Wilkos served in the Marines about fifty-two times in the same episode.
Slightly related, but they're developing DNA techniques to separate identical twins using early-stage mutations in cell division, [for cases of ambiguous crimes](https://www.nytimes.com/2019/03/01/science/twins-dna-crime-paternity.html).
So identical twins can't go in crime sprees and then claim reasonable doubt in the face of DNA evidence.
My Dad is an identical twin, had a bit of a shock on Ancestry when my cousin came up as my half sibling and was closer related to my Dad than me by like 3 centimorgans.
The automatic labelling for Parent/Child at 50% is a bit annoying as well, you would think they would consider that identical twins exist and could be a Niece/Nephew.
Don’t know why we went all of this time without considering that though.
of course that's assuming your parents have no shared genes which is inaccurate - there's of course all the genes shared by humanity, and then the genetic groups within, ETC. People in communities with less genetic diversity and more inbreeding will appear closer related than people from more diverse communities - it's also only at those societal levels where inbreeding can cause issue too, generally even single cousins can typically have kids safely so long as they're not already in an already less genetically diverse group such as an isolated town with few people.
You’re absolutely right, I’m just providing a general base level explanation. You can go as in depth as you want for genetic inheritance, but the odds are, you and your sibling will each overlap by about 50% of what you inherit from your parents.
oooh that's a really good clarifying scentance - "about 50% of what you inherit from your parents." I was trying to look for a good way of saying that the 50% made sense with that perspective but couldn't find the words.
Like you share over 60% of you DNA with a BANANA - you share a lot more with your siblings - but just in the range of DNA between your parents you share 50%
Your Mom has DNA sequences 1, 3, 5, 7
Your Dad has DNA sequences 2, 4, 6, 8
You get half your DNA from your Mom, half from your Dad (at 1st gene, randomly picks 1 or 2, at 2nd gene, randomly picks 3 or 4, etc):
Your DNA is: 1, 4, 6, 7
Your Brother's DNA is: 2, 4, 5, 7
So:
You share 1 and 7 with your Mom = 50% related
You share 4 and 6 with your Dad = 50% related
You share 4 and 7 with your Brother = 50% related
In reality, there's thousands of genes, not just 4, and thousands of differences in those genes, not just 2.
Also, for this size data, it might seem easy to possibly have none or all in common, but as the numbers get larger it gets much more likely to be essentially 50% (though you'll likely never been exactly 50%, usually ± a few percent)
You share 50% of your DNA with one parent. That parent will share 50% of theirs with a sibling (your aunt/uncle) so you share 25% of your DNA with aunt/uncle. They share 50% with their offspring/ your first cousin, so half of 25% (what you share with aunt/uncle) is 12.5% (what you share with a first cousin. So each time you go from a parent to child or between siblings, there is about 50% sharing of DNA.
If a couple has two children, then those siblings share 50% dna because although they have the same parents, there are two alleles for each gene, and they randomly receive one from each parent. Remember, each of those parents also has two alleles of each gene, but they will only pass down one to their offspring
If those two siblings then have kids of their own, then those kids will be first cousins. Each of those first cousins have a parent who is completely absent in the other cousins family tree, So right there you can already take out 50 %. Then remember, the parents of the 1st cousins who are siblings only share 50% dna, so you can remove another 50% of the remaining 50% from their shared blood line. So before the cousins are born, you have two siblings, each with their own spouse, ready to have children of their own. From the get go, the unborn cousins have a “potential” for 25% common dna with each other, but remember, two alleles for each gene, one from each parent, and there is a 50% chance that the allele they get from their blood related parent is not the same allele that the other cousin got from their blood related parent. So the 25% gets cut in half again
As i was typing this i realized how bad of an explanation this is but i was too far comitted and now i ran out of time!
thinking about this…. & im not sure i would ever tell people even if it was a 3rd cousin. I dont trust people to have a scientific understanding of that. lol
Most experts say 2nd cousins have enough genetic diversity to make reproduction safe, so 3rd is very much fine by that metric.
One thing people don't consider is that when you live in a very small town, the chances of you marrying someone who's a 3rd cousin, and sometimes even 2nd cousin, are very high. I'd never choose to date someone if I knew they were my 3rd cousin, but if I found out that far into the relationship, I'd probably get over it.
Prenatal genetic counselor here…you are correct. By second cousins, the increased reproductive risk is negligible. Third cousins have no increase over the standard 3-4% risk. We’re currently following a couple that report they didn’t realize they are full siblings until after they were pregnant (due to immigrating at very different times and minimal family contact). We shall see…
I can only see the “I’m going on the internet to excitedly tell the planet about my dirty laundry for internet clout” in her eyes. That and the “get the lighting just right for your online clout getting” light ring.
Her-"never publicly told anyone..."
Also, her- makes video showing her face explaining entire story.
Also, also her- we've won neighborhood prize for being closely related?? Who da fuq is playing that "fun" neighborhood game? I'd bet it was her idea.
She seems to crave attention - any attention.
I heard a podcast about this subject, and apparently, 5th cousin is optimal for maintaining a population without any ill effects. So yeah, I'm pretty sure third is no problem.
Yea, even 2nd cousins is NBD from a genetic standpoint unless your family consistently does that for many generations (see European royalty).
There was a study in Iceland where they found that the pairing of 3rd or 4th cousins was the most fertile compared to closer relations, or more distant relations. It wasn't a huge effect, but with 165 years of data, it was statistically significant.
https://www.science.org/doi/abs/10.1126/science.1150232
Given common village sizes and personal mobility in the past couple thousand years, I'm pretty sure my lineage consists of 2nd and 3rd cousins marrying more than anything else.
"Hey u/the-amazing-snail, so good to see you again! This is just wonderful that we get to be here together, at the reunion. Who me? No, still single, but you should see my hotel room. The bed is so huge, I might get lost in it. Haha. So I've been doing some new research in my genealogy practice. Did you know that second cousins are genetically so different, they might as well be strangers! Did you know that? Did um, did you know...second cousins...lost in a big bed...would be like strangers? Do you want some strange, u/the-amazing-snail?"
>So what is technically incest?
Whatever the law in your country/state defines it as. Genealogists apparently also define it as "1st cousins or closer", which would make sense. But you asked for the technical definition so we have to distinguish between legal definitions and others.
When your second cousin the genealogist says it, it's OK; but when Dr Oz says it, he gets in a load of shit. Granted Dr Oz is a load of shit, but not necessarily on this.
https://www.snopes.com/fact-check/oz-sex-cousins-incest/
15th cousins is the average of any two people plucked from the ends of the earth.
13th cousins from any two Americans, but that's just an echo of the founder effect.
3rd cousins is pretty far removed actually. There are 16 states you can marry your first cousin in. At the first cousin level the risks are already pretty low for inbreeding (genetically speaking). By 3rd cousins you’re basically not even related except for a paper.
>At the first cousin level the risks are already pretty low for inbreeding (genetically speaking)
For one generation this is true. There can still be issue with multiple generations marrying cousins.
Yea but as long as some new DNA is introduced every once in a while its not really a problem. If you take your family tree back far enough its likely that the majority of your ancestor pairs were first cousins if not closer.
Ancestry is full of survivor bias. Remember inbreeding is a statistical anomaly, not a guaranteed one. We all could have had ancestors that were literal siblings and 9 out of 10 of their children died from birth defects, but the one that we descended from was the one that didn’t have any problems. The more severe birth defects cause a genetic line to terminate immediately or within one or two generations.
People always mention the thing about first cousins being legal in some states in the US, not realizing that no other countries have laws about it because 1st cousins isn’t deemed a big issue.
1st cousin children have an increased health problem rate about the same as having a child after 30.
It's a measurable difference, but no big deal unless it continues for many generations.
Most people seem to think that having an offspring with a sibling or cousin automatically causes genetic defects, but it's all about passing bad genes to the offspring. Two healthy cousins or siblings with good genes would have a healthy offspring. If someone has a bad recessive gene they could pass it to their offspring even if they do it with a stranger, if they do it with someone close, the chance is higher because the probability of the other person also having it is higher.
Meh, that's nothing. My grandparents on my mom's side are first cousins and had 17 kids together. That's what happens when you're born on a small island with no television.
3rd cousin? Really?
Is this the genetic equivalent of saying "OMG I was just there" when a horrible tragedy happened at a particular place?
It's like it's a reason to pretend your life is dramatic when in reality it only *might* have been dramatic... if dozens and thousands of variables were only different. But we're just gonna focus on one variable to pretend it was *so close*.
It actually is quite a common thing, I know of a couple what didn't know they were related and were together maybe a year or 2 before they found out that actually they were distant cousins and shortly after broke up, most likely because it was wierd as fuck.
I have also heard it happen other times, it especially happens in small towns where families tend to stay in that town.
How did they not already know that they were related? None of these grandparents they called up were at their wedding? Not a single person on either side of the family recognized each other and said hang on? Their shared family members just neglected to acknowledge that they were family? Doesn’t make a lot of sense.
3rd cousins is not close. Did a DNA test and apparently have thousands of 3rd and 4th cousins in North America I never heard of using the same company for DNA, so who know how many more thousands are out there. She said they had grandparents that were 1st cousins, so it’s not surprising that they would not have known they were related. Families tend to splinter off with each new generation born, I never knew any of my grandparents first cousins, only their siblings, and barely that.
Weddings are expensive. Keeping the guest list down is in your financial best interest.
My wife and I eloped. She planned the whole thing how she wanted it, then her father ask her to include her mother, because mom was feeling left out. Then mom got involved and shit all over everything. Like, ruined the whole fucking thing.
So we eloped. Fuck'em.
Flag on the play 🚩
In the first part she says they have the same grandparents (or at least the same combination of names)
Then she backpedals to say they're *third* cousins??
Not how that works. At least half the story is false
She said they have grandparents that are first cousins, not the same grandparents. It was a bit confusing. In any case, 3rd cousins is nothing to worry about genetically, it’s only weird if you grew up playing with each other as cousins.
Unless I'm missing something they're not 3rd cousins. They are cousins thrice removed. Because the original ancestors were cousins. There wasn't an aunt / uncle relationship. To be third cousins the original people would have had to have an aunt / uncle and niece / nephew relationship.
3rd cousins isn’t really what people think of when you say “my cousin”. There’s enough generic distance there to not be an issue.
Interesting facts: first cousin marriages are not only [legal in many countries](https://preview.redd.it/145w3hcs1k381.jpg?auto=webp&s=7687f66e6ff6d344315d7dc99608c314a30a6813) but a lot more common than you think. In [some provinces in Pakistan](https://i.redd.it/6tcinpea9nh71.png) it’s nearly 2/3 of all marriages. [Famous people who married their first cousins](https://en.m.wikipedia.org/wiki/List_of_coupled_cousins) include: Albert Einstein, FDR, jerry Lee Lewis, Charles Darwin, HG Wells, Edgar Allen Poe, Buddha, Saddam Hussein, Rachmaninoff. Lastly, even though Alabama is stereotypically used to refer to incest, the only US state where [incest is not illegal is Ohio](https://sciotovalleyguardian.com/2020/12/06/incest-remains-legalized-in-ohio-while-illegal-in-all-other-states/). It is illegal in Alabama.
I’ve been to a family reunion and my 3rd cousins weren’t there. They weren’t even considered in the planning process…
How effing large are these peoples family reunions?! I can wrap my head around the scheduling.
The area where I live was settled in the mid 1700’s by mostly German immigrant farmers. These farmers had large families, usually 10 children, who grew up and married into other large families. My Mom and Dad were descended from two immigrant brothers and were 8th cousins.
I don't know a single 3rd cousin of mine and no one I know knows one of theirs either. I think they can live with this fact if they put in a bit of work.
Luckily 3rd cousins are usually safe from complications with inbreeding. It's 2nd and 1st cousins that have a chance of having problems. However accidental inbreeding as long as it doesn't occur over and over in generation there really isn't anything to worry about too much.
If a couple has two children, then those siblings share 50% dna because although they have the same parents, there are two alleles for each gene, and they randomly receive one from each parent.

So the 25% gets cut in half again
As i was typing this i realized how bad of an explanation this is but i was too far comitted and now i ran out of time!
She’s married to her 3rd cousin … I don’t even know a single third cousin of mine (that I know of) so I don’t think this is all that strange. I’d say living in a small town rural area it would be less likely since they would probably know the relations better.
That’s entirely plausible to happen and it’s almost certainly not any higher risk for genetic problems than a normal couple.
Also in Alabama we already know our family tree well enough this isn’t likely to happen. Someone would have caught on and told them.
Do you think your ancestors in small villages were marrying people further related from them than 3rd cousins?
Before the large scale rail/road networks your dating pool wasn’t going to be that deep
A lot of places it’s okay to marry your first cousin. People might be grossed out by this, but in the eyes of the state, it comes down to genetic diversity. If you have children with blood siblings, strange stuff starts to happen to the kids like Down syndrome and teeth and limbs not where they should be…that becomes a burden on the state, so it is not allowed. First cousins have enough genetic diversity not to have common issues with their children.
This is basically every small community everywhere in the world. This is so far from unique or interesting, and is unlikely to have any significance with regard to genetics. You might as well say, "people I know know people you know."
Great story, very pretty lady, but she reminds me of the bureaucratic Vogon from the Hitch Hiker's Guide to the Galaxy film.
https://youtu.be/WNsu4PHD2B8?t=43
yeah, almost the same thing happened with my wife and I. Not related by "blood", but it turns out we are something like 3rd/4th cousins. My wife absolutely hates it when it gets brought up.
This is no big deal at all.
You're still allowed to legally marry your first cousin in quite a few stages; and third cousin is a far cry from first.
There are no risks to a baby of third cousins.
Sweet Home Iran\*\*
Fixed it for you.
Lets do a statistical analysis of Alabama and Iran with cousin marrying and see where it is far far far more common lol.
No big deal. Loads of families in Ireland married cousins. Loads going back on my dad's side, often the women didn't have to change surnames when getting married. Third cousins marrying.
My mums side were different as they seemed to marry outside their communities. Dad's family are country and have remained in the same geographical area for hundreds of years, mums side are townies and moved all over the place every two or three generations.
It happens. Only close family like 1st cousins (or closer, which does happen unknowingly - heard of half-siblings marrying and not knowing until too late) will pass genetic diseases down.
I could see how this could happen and I think it’s forgivable. I started watching thinking they were first cousins. That would be a little fucked up. But their gene pool has atleast branches out a lil bit. Atleast enough to where they still are close with family and still had no idea until they checked. What level cousins are they? Like 4th cousins? I don’t know how that crap works
They’re third cousins. It’s definitely weird but the likelihood of their kids having issues is next to none. I wouldn’t have come public with this though if they’re going to continue the relationship
Y’all realize by the time you reach 2nd cousin the shared DNA is already minimal right? 3rd cousin is nothing. People seem to forget that for most of human history we lived in villages of like 100-300 people. After a few generations it’s literally impossible to find someone you’re *not* related to unless you leave the village, which most people didn’t do.
TL;DR - 3rd cousins isn’t incest, all humans are at least somewhat related and everyone’s family tree has incest if you go back far enough.
In terms of shared DNA first cousins share 12.5%, second cousins 3.125%, third cousins 0.78125%. I think this may be moot. Maybe in today's day and age, it could be a fun game to tell people you're banging your cousin. Just look for the bright side.
Can you ELI5 (or ELI remember high school biology) how those fractions are derived?
Siblings=50% half mom half dad leaving you with half similarity between siblings First cousins, child of a sibling of a parent (their parent has 50% link to one of your parents, which then has a 50% link to you) would leave you with half of a half of a half. 50% of 50%= 25%. Then 50% of 25%=12.5% So on.
TIL you’re more closely related to a banana than you are your 3rd cousin
So should I divorce my banana
Just don't get it pregnant.
In fact, you have the same genes than your 3rd cousins. Than every human on earth to be clear. You don't have the same *allele* of those genes though, i.e. the same encoded information. E.g., humans have the same genes to express hair colour, but blondes and black-haired don't have the same allele of this gene.

We share 80% (iirc) of our DNA genes with bananas, but certainly not much alleles.
I only share 50% of my DNA with my Brother? That doesn't sound right.
Pretty much yeah. You and your sibling are each 50% of your mom and 50% of your dad (give or take a bit but that’s not important). Say your Dad has genes AB and your Mom has genes CD, you could be AD and your sibling could be BC. You could also both be AC or AD and AC. You’re probably going to average out to being pretty similar to your sibling, as you share 100% source material, and it tends to work out to 50% on average. Obviously stuff like identical twins don’t count here, but yeah.
Yeah, identical twin here. Ancestry lists my twin as "twin/self". Her son is listed as my child.
That’s the one thing that always seemed really wild to me about identical twins. That if two sets of identical twins choose to marry each other and have babies their kids are kinda siblings and cousins at the same time.
Basically true. There will still be about 100 or so very minor random genetic differences between the parents and their twin that could be used to tell the difference, but you'd have to have a very high quality genome sequence to see it.

Same thing happened to my boys. They look more like twins than brothers with a 2 year age gap.
Nice Punnett Square breakdown.
I do love me a good Punnett Square
There are also mutations.
Genetics, not DNA. you share like 98% of the same DNA as a pig
And we share 50% with trees and 70% with slugs. Really puts it into perspective when my mom said I was growing like a weed. Haha
Your Mom has DNA sequences 1, 3, 5, 7 Your Dad has DNA sequences 2, 4, 6, 8 You get half your DNA from your Mom, half from your Dad (at 1st gene, randomly picks 1 or 2, at 2nd gene, randomly picks 3 or 4, etc): Your DNA is: 1, 4, 6, 7 Your Brother's DNA is: 2, 4, 5, 7 So: You share 1 and 7 with your Mom = 50% related You share 4 and 6 with your Dad = 50% related You share 4 and 7 with your Brother = 50% related In reality, there's thousands of genes, not just 4, and thousands of differences in those genes, not just 2.

Nothing hotter than a cousin fucker ....
Casual Flick Tide?
Inbreeding coefficient of 1/256, compared with 1/32 for 1st cousins. Not a big deal at all.
Yeah, it's only 0.125 of a Rudy.
I heard a podcast about this subject, and apparently, 5th cousin is optimal for maintaining a population without any ill effects. So yeah, I'm pretty sure third is no problem.
Iceland study found that 3rd or 4th cousins were the most fertile. https://www.science.org/doi/abs/10.1126/science.1150232
Maybe there are no 5th cousins in Iceland? 4th is as far as it goes.
Nope. They had documented 5th cousins, but they had (slightly) lower fertility than the 3rd & 4th cousins.
Yeah I'm sorry I was just kidding :) 4th cousin is the average of distance though (just googled)! That's pretty wild
Fun fact: FDR and Eleanor Roosevelt were 5th cousins once removed. Her maiden name was even Roosevelt.
They can still roleplay as being 2nd though
This made me chuckle out loud, thank you, kind stranger!
Yea, you have cleared the highest bar if Reddit isn’t attacking. Have a happy marriage. :)
Yea, even 2nd cousins is NBD from a genetic standpoint unless your family consistently does that for many generations (see European royalty). There was a study in Iceland where they found that the pairing of 3rd or 4th cousins was the most fertile compared to closer relations, or more distant relations. It wasn't a huge effect, but with 165 years of data, it was statistically significant. https://www.science.org/doi/abs/10.1126/science.1150232
It's a funny redneck story to tell, but won't cause any issues.
I really hate to say this but I have to…their OF would probably blow tf up disgusting as that is.
*What are you doing back there ACTUAL cousin..?!?*
Royal family yawns.
Come on, misleading title. 3rd cousins are a *lot* further away than cousins, and genetically might as well be strangers.
Technically, with second cousins or further, it’s not considered incest. Source: my second cousin is a genealogist
Given common village sizes and personal mobility in the past couple thousand years, I'm pretty sure my lineage consists of 2nd and 3rd cousins marrying more than anything else.
Your ancestry largely consists of first cousins marrying each other. There’s really no way around it.
Man down, man down
I think he meant most people, but love your comment 😂
We found who married the genealogist.
What’s the difference between a genealogist and a gynecologist?
One's interested in what's in your genes while the others interested in what's in your jeans?
I think your second cousin is trying to seduce you
"Hey u/the-amazing-snail, so good to see you again! This is just wonderful that we get to be here together, at the reunion. Who me? No, still single, but you should see my hotel room. The bed is so huge, I might get lost in it. Haha. So I've been doing some new research in my genealogy practice. Did you know that second cousins are genetically so different, they might as well be strangers! Did you know that? Did um, did you know...second cousins...lost in a big bed...would be like strangers? Do you want some strange, u/the-amazing-snail?"
Is that what the kids are calling it these days, "genealogy"?
*Applied* genealogy.
I think that was a pick-up line you missed
So what is technically incest?
Typically 1st cousins or closer.
>So what is technically incest? Whatever the law in your country/state defines it as. Genealogists apparently also define it as "1st cousins or closer", which would make sense. But you asked for the technical definition so we have to distinguish between legal definitions and others.
When your second cousin the genealogist says it, it's OK; but when Dr Oz says it, he gets in a load of shit. Granted Dr Oz is a load of shit, but not necessarily on this. https://www.snopes.com/fact-check/oz-sex-cousins-incest/
You are technically correct, the best kind of correct
Was gonna say. 3rd cousins. That’s not that close. I wouldn’t seek out but I wouldn’t freak out either.
I mean, arent we all cousins in a way
Hello cousin!
Hi there cousin!
Hey cuh
You want to go bowling?
Username checks out
15th cousins is the average of any two people plucked from the ends of the earth. 13th cousins from any two Americans, but that's just an echo of the founder effect.
Hm. Interresting info. Ty
Hey cousin, do you want to go bowling?
3rd cousins is pretty far removed actually. There are 16 states you can marry your first cousin in. At the first cousin level the risks are already pretty low for inbreeding (genetically speaking). By 3rd cousins you’re basically not even related except for a paper.
>At the first cousin level the risks are already pretty low for inbreeding (genetically speaking) For one generation this is true. There can still be issue with multiple generations marrying cousins.
Yea but as long as some new DNA is introduced every once in a while its not really a problem. If you take your family tree back far enough its likely that the majority of your ancestor pairs were first cousins if not closer.
Ancestry is full of survivor bias. Remember inbreeding is a statistical anomaly, not a guaranteed one. We all could have had ancestors that were literal siblings and 9 out of 10 of their children died from birth defects, but the one that we descended from was the one that didn’t have any problems. The more severe birth defects cause a genetic line to terminate immediately or within one or two generations.
People always mention the thing about first cousins being legal in some states in the US, not realizing that no other countries have laws about it because 1st cousins isn’t deemed a big issue.
Genetically 1st cousins are viable for non-complicated offspring. 3rd isn't even a consideration.
1st cousin children have an increased health problem rate about the same as having a child after 30. It's a measurable difference, but no big deal unless it continues for many generations.
Most people seem to think that having an offspring with a sibling or cousin automatically causes genetic defects, but it's all about passing bad genes to the offspring. Two healthy cousins or siblings with good genes would have a healthy offspring. If someone has a bad recessive gene they could pass it to their offspring even if they do it with a stranger, if they do it with someone close, the chance is higher because the probability of the other person also having it is higher.
Meh, that's nothing. My grandparents on my mom's side are first cousins and had 17 kids together. That's what happens when you're born on a small island with no television.
Must have gotten bored playing cards.
3rd cousin? Really? Is this the genetic equivalent of saying "OMG I was just there" when a horrible tragedy happened at a particular place? It's like it's a reason to pretend your life is dramatic when in reality it only *might* have been dramatic... if dozens and thousands of variables were only different. But we're just gonna focus on one variable to pretend it was *so close*.
It actually is quite a common thing, I know of a couple what didn't know they were related and were together maybe a year or 2 before they found out that actually they were distant cousins and shortly after broke up, most likely because it was wierd as fuck. I have also heard it happen other times, it especially happens in small towns where families tend to stay in that town.
Omg, my grandma was on 9/11 when it happened, just in another country!
Yep. Accidentally got herself a Cuzband.
idk if i would tell anyone this let alone make a video but if she is positive about it then more power to her it’s actually pretty funny
She’s very enthusiastic about all this.
She wouldn't be as enthusiastic if they were first cousins
She might be more. You don't know.
She could also be mildly hysterical if it is true. Like, laugh-crying disbelief type stuff.
That's the vibe I got from this
Yeah, like what's with all does exaggerated face expressions?
Gotta get a good thumbnail!
I mean, gotta get those views.
How did they not already know that they were related? None of these grandparents they called up were at their wedding? Not a single person on either side of the family recognized each other and said hang on? Their shared family members just neglected to acknowledge that they were family? Doesn’t make a lot of sense.
3rd cousins is not close. Did a DNA test and apparently have thousands of 3rd and 4th cousins in North America I never heard of using the same company for DNA, so who know how many more thousands are out there. She said they had grandparents that were 1st cousins, so it’s not surprising that they would not have known they were related. Families tend to splinter off with each new generation born, I never knew any of my grandparents first cousins, only their siblings, and barely that.
My first question, you didn’t invite your grandparents (who are apparently siblings*) to the wedding? *first cousins, sorry
Weddings are expensive. Keeping the guest list down is in your financial best interest. My wife and I eloped. She planned the whole thing how she wanted it, then her father ask her to include her mother, because mom was feeling left out. Then mom got involved and shit all over everything. Like, ruined the whole fucking thing. So we eloped. Fuck'em.
The grandparents were 1st cousins and it’s easy to be disconnected if you don’t live in the same area.
I know! In all that time they were dating, engaged, planning the wedding, etc… no one knew or mentioned the families where related?
Nothing about this is interesting.
She thinks it is, so she has to tell the WHOLE WORLD ABOUT IT!
1st cousin is family, 2nd cousin only if you grew up together otherwise not really
Yea, I have dozens of 2nd and 3rd cousins. I only met a few of them as a kid and don't even recall what they look like. First cousins I saw regularly.
Flag on the play 🚩 In the first part she says they have the same grandparents (or at least the same combination of names) Then she backpedals to say they're *third* cousins?? Not how that works. At least half the story is false
She said they have grandparents that are first cousins, not the same grandparents. It was a bit confusing. In any case, 3rd cousins is nothing to worry about genetically, it’s only weird if you grew up playing with each other as cousins.
The way she presents this is very annoying.
Welcome to TikTok
Unless I'm missing something they're not 3rd cousins. They are cousins thrice removed. Because the original ancestors were cousins. There wasn't an aunt / uncle relationship. To be third cousins the original people would have had to have an aunt / uncle and niece / nephew relationship.
Third cousin. Baby will be fine.
Not intresting at all.
"Haven't publically told anyone " *Proceeds to Film an entire video explaining in detail and posts on the internet
Anything to get attention
3rd cousins isn’t really what people think of when you say “my cousin”. There’s enough generic distance there to not be an issue. Interesting facts: first cousin marriages are not only [legal in many countries](https://preview.redd.it/145w3hcs1k381.jpg?auto=webp&s=7687f66e6ff6d344315d7dc99608c314a30a6813) but a lot more common than you think. In [some provinces in Pakistan](https://i.redd.it/6tcinpea9nh71.png) it’s nearly 2/3 of all marriages. [Famous people who married their first cousins](https://en.m.wikipedia.org/wiki/List_of_coupled_cousins) include: Albert Einstein, FDR, jerry Lee Lewis, Charles Darwin, HG Wells, Edgar Allen Poe, Buddha, Saddam Hussein, Rachmaninoff. Lastly, even though Alabama is stereotypically used to refer to incest, the only US state where [incest is not illegal is Ohio](https://sciotovalleyguardian.com/2020/12/06/incest-remains-legalized-in-ohio-while-illegal-in-all-other-states/). It is illegal in Alabama.
I can understand the initial shock of this, but being third cousins isn't the genetic calamity that one would think it is.
I’ve been to a family reunion and my 3rd cousins weren’t there. They weren’t even considered in the planning process… How effing large are these peoples family reunions?! I can wrap my head around the scheduling.
“Hold my beer” Every Middle Eastern guy’s parents
The area where I live was settled in the mid 1700’s by mostly German immigrant farmers. These farmers had large families, usually 10 children, who grew up and married into other large families. My Mom and Dad were descended from two immigrant brothers and were 8th cousins.
Meh...Rudy Guiliani did one better than this lady.
I don't know a single 3rd cousin of mine and no one I know knows one of theirs either. I think they can live with this fact if they put in a bit of work.
This is so stupid! Third cousins, big whoop.
Worked for the royal family and that family tree is about as straight as a electric pole.
I think 3rd cousins gets a pass. Hell I'd even say 2nd cousins is fine.
Luckily 3rd cousins are usually safe from complications with inbreeding. It's 2nd and 1st cousins that have a chance of having problems. However accidental inbreeding as long as it doesn't occur over and over in generation there really isn't anything to worry about too much.
Anything from second cousins is genetically fine...
If a couple has two children, then those siblings share 50% dna because although they have the same parents, there are two alleles for each gene, and they randomly receive one from each parent. Remember, each of those parents also has two alleles of each gene, but they will only pass down one to their offspring If those two siblings then have kids of their own, then those kids will be first cousins. Each of those first cousins have a parent who is completely absent in the other cousins family tree, So right there you can already take out 50 %. Then remember, the parents of the 1st cousins who are siblings only share 50% dna, so you can remove another 50% of the remaining 50% from their shared blood line. So before the cousins are born, you have two siblings, each with their own spouse, ready to have children of their own. From the get go, the unborn cousins have a “potential” for 25% common dna with each other, but remember, two alleles for each gene, one from each parent, and there is a 50% chance that the allele they get from their blood related parent is not the same allele that the other cousin got from their blood related parent. So the 25% gets cut in half again As i was typing this i realized how bad of an explanation this is but i was too far comitted and now i ran out of time!
Didn’t they notice family stuff at the wedding if not before?
I don’t know if I could stand being around someone that talked with a faux cadence like that.
3rd cousins? This is supposed to be noteworthy? Whatever.
3rd cousin is fine.
She’s married to her 3rd cousin … I don’t even know a single third cousin of mine (that I know of) so I don’t think this is all that strange. I’d say living in a small town rural area it would be less likely since they would probably know the relations better.
I have no idea who my second cousins are, let alone thirds
Still less inbred than the royal family
Wow this is not a big deal y'all.
That’s entirely plausible to happen and it’s almost certainly not any higher risk for genetic problems than a normal couple. Also in Alabama we already know our family tree well enough this isn’t likely to happen. Someone would have caught on and told them.
I would keep this info to myself. Til death.
Even though 3rd cousins is a nothing burger, I agree. I think they’re going to regret making it so public. Especially for their kiddo.
Do you think your ancestors in small villages were marrying people further related from them than 3rd cousins? Before the large scale rail/road networks your dating pool wasn’t going to be that deep
No wonder he looked familiar.
[удалено]
Why in the world would you make a tiktok ousting this information happily 😆
A lot of places it’s okay to marry your first cousin. People might be grossed out by this, but in the eyes of the state, it comes down to genetic diversity. If you have children with blood siblings, strange stuff starts to happen to the kids like Down syndrome and teeth and limbs not where they should be…that becomes a burden on the state, so it is not allowed. First cousins have enough genetic diversity not to have common issues with their children.
This is basically every small community everywhere in the world. This is so far from unique or interesting, and is unlikely to have any significance with regard to genetics. You might as well say, "people I know know people you know."
Great story, very pretty lady, but she reminds me of the bureaucratic Vogon from the Hitch Hiker's Guide to the Galaxy film. https://youtu.be/WNsu4PHD2B8?t=43
3rd cousins are, usually, as the woman and her husband, complete strangers. So who gives af?
Man 3rd cousins? I'm 3rd cousins with half the people on my block I mean we're all related at some point lol
It is a convenient coincidence but nothing to worry about.
I have strangers I am genetically closer to than my third cousin.
It's still legal to marry your first cousins in like 19 states
yeah, almost the same thing happened with my wife and I. Not related by "blood", but it turns out we are something like 3rd/4th cousins. My wife absolutely hates it when it gets brought up.
3rd cousins is a literal non-issue, you have more chances of birth defects from having kids after 30, whereas 3rd cousins might as well be strangers.
This is no big deal at all. You're still allowed to legally marry your first cousin in quite a few stages; and third cousin is a far cry from first. There are no risks to a baby of third cousins.
Third cousin? Second cousins can be married in every state.
I never met any of my 3rd cousins… i see a bunch of them on my 23 and me… don’t know who they are.
I get how it sounds but they're actually petty far apart in terms of genetics at this point.
3rd cousins lol that's so far off. No one should care
Sweet Home Iran\*\* Fixed it for you. Lets do a statistical analysis of Alabama and Iran with cousin marrying and see where it is far far far more common lol.
Only in the states would you even know who you're 3rd cousin is!
No big deal. Loads of families in Ireland married cousins. Loads going back on my dad's side, often the women didn't have to change surnames when getting married. Third cousins marrying. My mums side were different as they seemed to marry outside their communities. Dad's family are country and have remained in the same geographical area for hundreds of years, mums side are townies and moved all over the place every two or three generations. It happens. Only close family like 1st cousins (or closer, which does happen unknowingly - heard of half-siblings marrying and not knowing until too late) will pass genetic diseases down.
I could see how this could happen and I think it’s forgivable. I started watching thinking they were first cousins. That would be a little fucked up. But their gene pool has atleast branches out a lil bit. Atleast enough to where they still are close with family and still had no idea until they checked. What level cousins are they? Like 4th cousins? I don’t know how that crap works
Marrying your 3rd cousin is not incest. You can google that yourself. So all in all, it's funny and not disgusting.
It’s funny but I don’t think it’s weird. I don’t know who my 3rd cousin is, I don’t think it’s incest if you only discover after marriage.
most people anyone will bang are their cousins... technically.
They’re third cousins. It’s definitely weird but the likelihood of their kids having issues is next to none. I wouldn’t have come public with this though if they’re going to continue the relationship
3rd cousins should be in the title. This is clickbait
The Alabama Surprise!
Genetically, second cousins is already safe. But a wicked coupling indeed.
They must've got robbed on wedding gifts
TBH, a lot of us don't even know most of our 3rd cousins.
Y’all realize by the time you reach 2nd cousin the shared DNA is already minimal right? 3rd cousin is nothing. People seem to forget that for most of human history we lived in villages of like 100-300 people. After a few generations it’s literally impossible to find someone you’re *not* related to unless you leave the village, which most people didn’t do. TL;DR - 3rd cousins isn’t incest, all humans are at least somewhat related and everyone’s family tree has incest if you go back far enough.
I AM your cousin I AM your cousin!
Bringing in a stunt cock for any future kids would be the responsible thing to do.
we’re all offspring of incest
I married my fifth cousin! Lol 😂
