That is the problem. With the pureblood politics, they would have extinct 
themselves out. We can resort to the 10-15% rule, those childs are not from 
the father they are supposed to be, so population is healthier in genepool 
terms. But so, I've asked a Biologist/Biochemist friend of mine about WW, 
described him eye colors, hairs, families, pureblood rule, and he says he'd 
want more facts, but he thinks the population is inviable unless you marry 
muggles, the more if we are talking of hundreds of years. To maintain red, 
black as raven (wich is not so common even in Spain, when the population 
ranges from light brown to black, usually) and albins as Malfoy you need a 
huge pureblood population, unless you resort to muggles, Veelas and the like.

Any thoughts?
