Do the children of two Magical parents have an advantage? If they do then selection based on blood purity has validity and merit. 

Neri:
This idea is a common mistake, regardless of the moral issues. 

<Snip> This is why crossbreeds are often stronger and healthier than both pure-blood parents. When 
people want to breed animals for ability, such as faster horses or cows with more milk (as opposed to show animals that are only supposed to conform to some "ideal" model) they are constantly bringing in new blood into the lineage, or they quickly arrive at a dead end.

Lynette:

Neri is very correct and you only have to look at those groups, who interbred because of "pure blood" reasons (the royal houses of Europe and the resulting blood diseases) or religion (the eastern European Jews and Tas Skas (sp?) disease) or geographic isolation (Cajins and several rare genetic diseases).   If these groups had added new blood and not internamed with first through third cousins, the genetic diseases would have not been seen, but have only been producing less and less carriers.  You have to have 2 carriers marry and then you would only get 1 out of 4 chances with the disease, 2 chances of carriers, and 1 chance of non-carrier.
