-Which risks? The risks so far mentioned in this thread are hopelessly misrepresented. One might make the argument that no such risk exists at all, or in any greater measure than that shared by couples of moderately dissimilar (all the rest of us - moderate at best) genetic lineage.
The explanation for why there is a risk of that a newborn gets some sort of mental disorder even when his parents are from different families is because our very far ancestors have most likely committed incest not understanding the unwanted effects of these relationships. Back then, there were less people than today and genetic diversity of the human race was low. As history passed, more and more people came to Earth, and as an effect of that, genetic diversity of humans got high. When genes that transfer information for cognitive abilities collide, there is a 89.7% chance that the product of this collision will either have some sort of mental disorder or retardation. When a brother and sister have sex, chances that the genes that transfer information for cognitive abilities will have a collision are increased by 50%. I was thinking that vorlon13, in the core of what he was trying to say, was right. I didn't pay much attention of how he tried to explain it nor if he has by any chance misrepresented it, sorry.
