If Shinji and Rei had a daughter together, wouldn't it just be Yui?

If Shinji and Rei had a daughter together, wouldn't it just be Yui?

Would it be deformed?

No, it'd be (You).

Let's assume Rei is a 100% genetic clone of Yui.
Shinji is genetically 50% Yui, 50% Gendo.

Children inherit 50% of each parents genetics. However, it's obviously not the case that it's the same 50% distribution each time- which is why two biological brothers aren't genetically identical.

A child between Shinji and Rei would theoretically be 75% Yui, 25% Shinji, but really it'd be 50% Yui, 50% Shinji's Yui+Gendo amalgamated genes.

So, in short, no.

Very likely retarded, incest is not ok for reproduction

one generation of incest is unlikely to have serious negative effects besides a higher likelihood of inheriting recessive hereditary diseases

This
Not particularly, unless you have a family history of retardation. Incest just makes it more likely for your children to inherit recessive traits, since if you have it, your sibling can also have it

Acccording to meme, where Rei is 50% Yui and 50% Lilith
Shinji: 50% Yui 50% gendo

Still enough for down syndrome(highest chance) and other strange shits to occur. More "same" genes = bigger chance for "shit"

This type have it guarranted to get at least 1

Shinji would never stick his dick in that creepy bitch, so it doesn't matter.

If this is the case, Rei and Shinji are, genetically speaking, identical to half siblings.

I don't think there'd be a problem with them procreating, or I think the risks would be minimal. Especially so considering Lilith (presumably) has DNA which is very different from Shinji's.

According to catholics, 4th kinship can be dangerous but only after med says so. Without knowing how parents and grandparents look like in genes its hard to say if particular anomaly will occur. 5th kinship is ok
But that's catholics, and japs like incests

There's another problem: Rei doesn't eat meat and have problem with maintaining "form". In short, giving birth to child would break her body or something

I realized yet again how creepy the pairing Shinji x Rei is/would be.

She is his mother, technically.

very oedipal

Outbreeding has disadvantages too. The most advantageous form of procreation with respect to passing on strong alleles is to do it with someone who is genetically similar... but not too similar. In fact, organisms are programmed to seek mates who seem 'somewhat' similar to themselves.

Genetic diversity doesn't always produce stronger offspring, this is a misconception.

So the Catholics are wrong, is what I'm saying.

But in Rei's case, yes, I don't see her actually being able to sire a child. This was more of a hypothetical discussion.

I don't think she's his mother genetically. Yui didn't have blue hair or red eyes so her DNA has obviously been altered. She's probably more comparable to a sister genetically.

I thought Rei was a full Yui clone with Lilith's soul?

>In fact, organisms are programmed to seek mates who seem 'somewhat' similar to themselves.
This is also why close relatives who meet for the first time during adulthood are so likely to fall in love with each other.

Every time you have inbreeding in a cosmic horror story, Lovecraft's corpse gets an erection.

Rei most likely can't have children with human males. She is partly Lilith i.e. note human. On genetic level Shinji is closer to a chimpanzee than to her.

Actually, genetic similarity between humans and chimps is around 98,8%, while descendants of Adam are similar to humans at 99,89%. I guess Lilith, whose blood is the source of human life would be even more close.

Lilith is the the source of all life on Earth, from humans to green moss, Lilith's DNA is all-embracing so it cant be similar to humans.
