a lot of intermarriage between, at most, distant cousins must have

JW:
As we saw on the Black family tree, marriage between cousins is 
commonplace, ans all purebloods have intermarried.  

Certainly among all purebloods, and also predominately among 
halfbloods, everybody is related to everybody.  If not for 
muggleborns, the WW would have hit a genetic brick wall centuries 
ago.  Everyone would be like the Gaunts, the result of inbreeding.

In the RW, the extremely interesting genetics results can occur when 
highly inbred animals or plants are bred with subjects completely 
outside their genetic line.  It is no surprise that unusual wizards 
such as TR and HP are the results of purebred - even inbred - wizard 
families marrying muggles or muggleborn.
