Inbreeding = higher chance on genetic diseases or if you don't believe me Coefficient of relationship and Inbreeding. Now let's say the mother has a recessive gene which causes Huntington (or any other disease) and she gets kids. The kids now both have that recessive gene. If the brother and the sister decide to produce offspring then there is a 25% chance that any one of their kids has the recessive gene twice and thus getting the disease. If two strangers produce offspring then there is very little chance that any of their children will get the actual disease, they may become a carrier but that's as far it will go.
(click to show/hide)As for the list of diseases that have a way higher chance of occurring with inbreeding and cause mental retardation:
http://en.wikipedia.org/wiki/Fanconi_anemia
http://en.wikipedia.org/wiki/Tuberous_sclerosis
http://en.wikipedia.org/wiki/Galactosemia
http://en.wikipedia.org/wiki/Angelman_syndrome
http://en.wikipedia.org/wiki/Cri_du_chat
http://en.wikipedia.org/wiki/Trisomy_18
I bet there are more than just these. Some are very rare 1/350000 people and some are as common as 1/3000 people. Now when inbreeding you raise the chance of all these diseases to considerable levels. And while it doesn't always happen I wouldn't want anybody to take the risk.

Well, while I do agree that with inbreeding you'll get children who'll probably have an autosomal recessive disease, the risks of developing Angelman, Cri-du-chat and Edward's disease (trisomy 18) are most likely the same, since the first one is related to genetic imprinting, the second is a deletion which usually appears spontaneously and the third one is a numeric anomaly (3 copies of the 18th chromosome instead of 2). Also, tuberous sclerosis is autosomal dominant, so it's not a good example because at least one of the parents manifests symptoms, and his/her baby will have the same risk of inheriting the disease - the other parent doesn't matter (unless he/she also suffers from the disease, then the risk is at least doubled).
Fanconi anemia and Galactosemia are Autosomal recessive diseases and inbred children have a much bigger chance of inheriting them, though Fanconi Anemia does not usually cause mental retardation (it only increases the risk of developing cancers, since an enzyme involved in DNA repairing is damaged/absent) and Galactosemia only causes brain damage if it is not diagnosed at birth (and there's a quick screening available for it) and/or if the child does not follow the recommended diet (no food containing galactose or galactose compounds).

Ok I may have chosen some bad examples but that's because I'm no doctor or geneticist but my point still stands. Even if the disease itself doesn't directly causes retardation then just having it will cause it as the child won't be able to fully concentrate on education, or even concentrate at all. And if the future children can't concentrate on education then all the higher educated people will disappear and thus society becomes stupid.

He's talking about diseases which kill, maim, and cripple little kids and you still care about whether they're mentally deficient.

Ok let's just come to the conclusion that inbreeding brings forth horrible diseases and for that sole reason it should be forbidden and fortunately it is. But the original question was "Incest = retarded children?" and thus I focused on that aspect more than on the others.

I think Soul is just jealous, because he doesn't have a sister of his own to fuck.

In fact I do have a sister but she's the worst sister ever. She always makes me look like the perpetrator and gets away with it a lot too. Dammit my parents even thought that I smoked while she was the one that did. And my parents are really against smoking so imagine what kind of scolding I had to endure because of that evil bitch....

Maybe she's tsundere for you? Or trying to get your attention that way? :D Maybe she's acting like that girl from Ore no Imouto, only with more incest-craving.
