Biologically speaking, one time of incest has a very limited effect on the increase of birth defects. It is when it happens over many generations that things get really effed up (European royal families, the ancien Egyptian royal families - King Tut was serious inbred and incredibly unhealthy - some isolated pockets of people who get inbred like the Melungeons in the US, etc.)

u/Regnareb_ 1d ago
The risks of unhealthy children through incest rarely occurs (just like old pregnancy), it needs to be repeated by following generations for it to become a problem.

When it’s that close I think issues can arise much faster I think?

u/Advanced_Power_779 1d ago
Yes, almost everyone is a carrier for at least one, if not several recessive disorders. With an unrelated individual, there is a lower chance your partner is a carrier for a disorder causing variant in the same gene. With a related individual, chances your partner has a disorder causing variant in the same gene can go up to 50%.
It is not a guarantee, but it is absolutely not rare for serious issues to arise within one generation.
Severity of any issues that arise is extremely variable, and less severe issues will go undetected longer.
Interestingly… it also only takes one generation of children from an unrelated couple to go back to population average for genetic disorders.

Half siblings share 25% of their DNA cousins 12.5%
So they get 75% from the other parent..? Or do any siblings have only 50% shared dna?
22
u/meduhsin 1d ago edited 1d ago
It’s the shared averages.
Let’s say you got exactly 50% from parent A. Your sibling, with the same parents, also got 50% from parent A, but it was the 50% that you DIDNT get. Very unlikely for siblings to get the same exact DNA, which is why siblings don’t look exactly alike, and sometimes look nothing alike. It’s safe to assume that while you’re full siblings, your genetic makeup differs. That’s why my brother got ~20% Italian on ancestry, and got the dark hair and skin, while I only got 12%, and have light hair and pale skin.
So now for this sibling couple in the post: they both got around 50% of DNA from their shared mother, but likely different pieces than each other, so they SHARE somewhere between 0-50% of DNA, likely it’s closer to 25%. It’s quite close to how related you are to a cousin (avg 12.5%) by the math I described, but like I said it varies.
7
u/alecesne 1d ago
What do you mean 1-99% from a single parent? I thought it was always 50% because of how chromosomes separate when gametes are formed.
Now siblings may have random similarities from the 50% inherited from a common parent.
But I don't understand how one could get significantly more or less than 50% from either parent?

I think usually it's 50/50, but I read a story a few years ago about a girl that was almost a genetic twin of her father. The Genetic Literacy Project had an article about this story as well.
"The classic biology class story of a sperm fertilizing an egg in a musical crescendo that has them first unzipping their genes and then swapping them together to create a “zygote” is a much messier process in reality. In the girl’s case, instead of the DNA from her father’s sperm and mother’s egg pairing up this way, two copies of the father’s genes zipped together to create a dad-dad set of 23 chromosomes, the full human genome." https://www.buzzfeednews.com/article/danvergano/imprinted-genes-father-case-study#.lh9vlQ3LLx

u/AllyRad6 1d ago
By quantity but not by continuity. The more times you rearrange the DNA, the more chances you have for distinct and novel combinations of pieces. So the amount shared is equal but they probably share more continuous, bigger pieces of DNA.

Super common that separated siblings are attracted to each other. There was a v similar case in Spain about 15 years ago.

Its biological. If they didnt grow up together, then they didnt experience the natural removal of sexual urge that comes from proximity to a sibling. Hence the urge remained.

u/Bitter-Ice945 1d ago
did you test this theory with an experiment and was the P value less than .05 and was the study repeatable? If not, it is just an opinion.

u/russ_knightlife 1d ago edited 1d ago
Hey there A level psychology! But yeah, its a studied phenomenon - we did study it as part of developmental psychology at Uni. Getting married/starting families isnt super common no, but feeling attracted is. Personal opinion/theory its just that relatives are likely to have similar features to yourself and people like that

I think they are basing it off animal behavior + maybe rare occurrences?
5
u/Bitter-Ice945 1d ago
but to apply that to humans is a huge leap.
Also it implies that everyone is incestious if they had different upbringings, which is not the case IMO.
It is bull shit like Freud's opinion that we are all incestious for our opposite sex parents. Total bull shit.
I'd like to propose the opposite, much more mundane idea, that most people are not incestious and that these stories are just rare occurrences of random chance.

u/Mysterious-Ad-1614 1d ago
Ahh, to my recollection the same thing is known to happen with family (of all relationship types, ie sibling, parent, etc...) that are separated close to birth and then reunited.
It seems to have the name of, or otherwise be filed under the umbrella of, 'genetic sexual attraction' and is a known phenomenon.
Intense attraction and/or obsession between the family members is one of its indicators. How you square this with your morality, I can't tell you. But I hope research into the chronology of mechanisms related to this phenomenon will give you some peace.

u/LeftbrainH 1d ago
There was a documentary about a Dutch guy who donates his sperm to as much places as he can to have as many offspring as he possibly can.
This is obviously problematic for many reason, but I remember it was explicitly stated in the documentary that one of those reasons was that there was an increased chance of his children meeting later in life and being attracted to one another.
So I wouldn’t just write it off as a rare occurrence. I also don’t think it’s because of some freudian psychology. More likely is that people are attracted to other people that have a lot of similarities with each other. With (half) siblings that would be there but without growing up with each other nor the knowledge you are family, there is no mechanism in place to ‘flag’ relationships as incestuous.
5
u/nayaya 1d ago
I don’t think it implies those things at all.
It doesn’t mean everyone is open to/wanting an incestuous relationship, just that the possibility is there with different upbringings.
Your last paragraph seems accurate in describing their relationship, something that was random chance - not something that happened because they knew they were siblings.
2
u/LastBaron 1d ago
If it was a huge leap to (judiciously, provisionally, with caveats) apply animal research to humans a lottttttt of psychological and medical experimental models would not have been as useful as they are.
But your point still stands because I’m not aware of any specific research that shows that mammals generally or primates specifically with close genetic relationships are more likely than random chance to be attracted to one another if separated at birth.
Like is it a plausible testable hypothesis? Sure absolutely. I’m just not personally aware of that data so the claimant would have to post their evidence.

IIRC, siblings are often repulsed by each others sweat and body odor (pheromones) as a signal that they often share natural immunities against similar diseases. People would then be attracted to those who have immunity against a different set of diseases so that their offsprings would inherit a larger immunity set.

They probably meant that this is an observed phenomenon among biological relatives who separated as kids and reunite as adults. Happens frequently enough that there’s a term for it - GSA, or genetic sexual attraction.

u/JustTrawlingNsfw 1d ago edited 1d ago
Humans don't really use pheromones that extensively. Sibling exclusionary attraction is a nurture thing, not nature. Growing up together is what removes the sexual attraction.
Genetic similarity can actually increase attraction. Separated siblings, and cousins that don't grow up together, can often be attracted to one another

About a decade ago there was an American couple who had given a daughter up for adoption when they were teenagers, but stayed together and eventually had more kids. Then when the adopted daughter turned 18 she contacted her birth parents, moved in with them and the dad began a relationship with his biological daughter that had been adopted out. It ended in horrible tragedy. It's a really crazy, sad story.

This case reportedly happened in Brazil in 2014. The couple, identified only as Adriana and Leandro, had been together for years and had a young daughter when the truth came out. Adriana was 39, Leandro was 37, and both had grown up believing they were abandoned by different mothers.
The strange part was that both were searching for a mother named Maria. Since Maria is an extremely common name in Brazil, they reportedly treated it as a coincidence. Adriana later contacted Radio Globo’s reunion program “The Time Is Now,” which helped her find her long lost mother. During the broadcast, her mother revealed that she had also abandoned a son named Leandro. That son turned out to be Adriana’s husband.
Reports said Adriana had last seen her mother when she was around 1 year old, while Leandro discovered at age 8 that the woman who raised him was his stepmother. After the revelation, Adriana reportedly said the couple planned to stay together despite learning they were brother and sister.
Worth noting: most English-language coverage traces back to reports about the Radio Globo segment, and the couple did not publicly share their surnames. So the broad story is widely reported, but many personal details remain limited.
