Heh, second cousin is far enough.

[-] MonkderVierte@lemmy.ml 41 points 6 months ago

Second cousin means cousin second order (grandchild of a sibling of one of your grandparents), right?

[-] Robust_Mirror@aussie.zone 14 points 6 months ago

Another way I like to think of it is it's your parent's cousin's kid. So you can see why from their perspective it would feel more closely related, it would be like you having a kid and your cousin having a kid and then you seeing them together.

[-] captainlezbian@lemmy.world 5 points 6 months ago

Yeah, genetically don't make a habit of it, but you're probably fine (unless your grandparents are identical twins or has hapsburgs or something), but also I'd be super uncomfortable if it was my kid

[-] ReeferPirate@lemy.lol 6 points 6 months ago* (last edited 6 months ago)

A parent's first cousin. Your first cousin's child would be a first cousin once removed.

banjos quietly play in the background

[-] MadBob@feddit.nl 76 points 6 months ago

That happened to a few of my cousins years ago. We were at a family function so I thought they would've put two and two together, but alas.

[-] victorz@lemmy.world 20 points 6 months ago
[-] MadBob@feddit.nl 12 points 6 months ago

I saw that after pressing send and thought to myself, ah, no one'll pull me up on that.

[-] captainlezbian@lemmy.world 10 points 6 months ago

It's ok I wouldn't want to admit it if my family reunion turned into an orgy either

[-] Stamau123@lemmy.world 6 points 6 months ago

They just got a good vibe, you know?

[-] victorz@lemmy.world 6 points 6 months ago

Sounds like it, cuz.

[-] OsrsNeedsF2P@lemmy.ml 72 points 6 months ago

Isn't there some sort of biological thing where you're more likely to be sexually attracted to your relatives if you don't know they're you're relatives

[-] olosta@lemmy.world 99 points 6 months ago

Second degree cousins is not that close though. If every generation has three children, that's 27 persons. I thinks that for most of human history excluding second degree cousins from the acceptable partners pool would have been impossible. Communities were not that big.

[-] spankmonkey@lemmy.world 19 points 6 months ago

Second degree cousins

I can't stop laughing.

[-] Enkrod@feddit.org 7 points 6 months ago

That's how it's phrased in many other languages, german for example.

[-] BruceLee@sopuli.xyz 5 points 6 months ago

French also

[-] HonoraryMancunian@lemmy.world 12 points 6 months ago

And if my maths is correct, you only share on average 12.5% of your DNA with them

[-] mEEGal@lemmy.world 28 points 6 months ago

your math may be wrong, because we have very similar genomes, even compared to complete strangers. hell, even between some species.

[-] HonoraryMancunian@lemmy.world 22 points 6 months ago

Well, yes. I meant in the sense we share on average 50% with each parent/siblings, 25% with grandparents, etc. I should have said genetics instead of DNA.

[-] Knuschberkeks@leminal.space 12 points 6 months ago

iirc 90% of dna is the same even between humans and plants. (Don't quote me on that)

[-] porous_grey_matter@lemmy.ml 6 points 6 months ago

Of the variable alleles, not all DNA

All I could find on this is something called "genetic sexual attraction" ^[1]^, though Wikipedia contains arguments that it's pseudoscience ^[1.1]^. Here's a Reddit post asking about this. ^[3]^.

Related to this, I also came across the "Westermarck effect" ^[2]^ which appears to suggest that people who grow up together are less likely to be romantically attracted to each other ^[2.1]^.

    1. §"Criticism"

      Critics of the hypothesis have called it pseudoscience. In a Salon piece, Amanda Marcotte called the concept "half-baked pseudoscientific nonsense that people dreamed up to justify continuing unhealthy, abusive relationships".[8] The use of "GSA" as an initialism has also been criticized, since it gives the notion that the phenomenon is an actual diagnosable "condition".

      Many have noted the lack of research on the subject. While acknowledging the "phenomenon of genetic sexual attraction", Eric Anderson, a sociologist and sexologist, noted in a 2012 book that "[t]here is only one academic research article" on the subject, and he critiqued the paper for using "Freudian psycho-babble".

    1. The Westermarck effect […] is a psychological hypothesis that states that people tend not to be attracted to peers with whom they lived like siblings before the age of six.

Yeah, that's weird: genetically similiar people are more attractive (as long as it isn't too similiar)(people in stable relationships often look alike) but bigger genetical difference is better.

[-] june@lemmy.dbzer0.com 7 points 6 months ago

Yes, one of the primary components of attraction is familiarity. Also proximity and similarity.

[-] rayquetzalcoatl@lemmy.world 64 points 6 months ago

Second cousins is kissing cousins, have at it!

[-] HollowNaught@lemmy.world 42 points 6 months ago* (last edited 6 months ago)

A lot of people here are saying that the more genetically similar you are to somebody, the more attractive they are (so long as you don't grow up with them). I'm here to tell you that those guys are completely wrong

Studies have shown that (in other animals unfortunately, not in humans) that the more genetically dissimilar two individuals are, the more attracted they are, so long as they can produce viable offspring (aka they can have kids)

This study would also be done on humans, but that would be slightly morally questionable

This is an evolutionary trait in order to incentivise us to increase the gene pool when possible. You can imagine what would happen if we only rucked our cousins (look at the royals)

Yeah you often strive for maximum compatible difference. There's no instinct to create a family ladder

Eh second cousin marriage isn’t a big deal in some cultures

[-] BruceLee@sopuli.xyz 12 points 6 months ago

*Most of cultures

[-] _cryptagion@lemmy.dbzer0.com 24 points 6 months ago

I used to work with this absolute idiot when I was a kid. He was married to his cousin. But apparently he was such a gross dude, that it was too much for her, so she left him. For his brother. She ended up having a couple kids, one with each brother.

Talk about going out of your way to keep it in the family. Their family tree was tied in a knot.

[-] Krauerking@lemy.lol 22 points 6 months ago* (last edited 6 months ago)

Oh hey look. The story of how Rudy Giuliani found his wife!

Edit: ex wife, sorry forgot the church didn't condone their boning like they wanted so they had to get a divorce.

[-] Earflap@reddthat.com 21 points 6 months ago

This is the only one that isn't fake

[-] some_guy@lemmy.sdf.org 14 points 6 months ago

Erotic fan-fic at its finest.

[-] gilarelli@jlai.lu 13 points 6 months ago

Careful anon, that's how you get a Habsburg child

[-] EvilCartyen@feddit.dk 68 points 6 months ago

I mean, probably not with a second cousin, unless you do it for hundreds of years. Greater risk of birth defects if you have children over 30.

[-] Zagorath@aussie.zone 27 points 6 months ago

Yeah even first cousins are actually not that bad, biologically speaking, if it's only done for one (or probably even two?) generation.

[-] sugar_in_your_tea@sh.itjust.works 5 points 6 months ago

Yup, and AFAIK, it's legal in some areas to have kids with your first cousin.

[-] Revan343@lemmy.ca 7 points 6 months ago

Probably legal in more places than it's illegal

And at this point, with all of the toxins from food processing/preservatives and the plastics getting into our bodies, the added risk is probably negligible.

[-] schizolol9@lemy.lol 10 points 6 months ago* (last edited 6 months ago)

Reminds me of the time I fucked my cousin a few times. She moved I now miss her.

Second cousins you don't share even blood

Comment:

Second cousin in my country is a cousin from the part not related to any of my parents of one of my cousins. What is weird of that?

For example, my cousin is one of my father's brother son, then my second cousin has to be (otherwise would be a cousin too) the daughter of the cousin's mother's brother.

If I pick a random girl I would be equally related genetically.

[-] Revan343@lemmy.ca 13 points 6 months ago

Uh...yeah you do. Just not very much of it

[-] scutiger@lemmy.world 19 points 6 months ago

I don't share my blood with anyone. You keep your grubby hands to yourself.

[-] LostXOR@fedia.io 5 points 6 months ago

People like you are why vampires are almost extinct. Be considerate and share a little.

This is a place to share greentexts and witness the confounding life of Anon. If you're new to the Greentext community, think of it as a sort of zoo with Anon as the main attraction.

Be warned:

If you find yourself getting angry (or god forbid, agreeing) with something Anon has said, you might be doing it wrong.
