(i'm jdr, a new kid)
We know (Ron mentions it at one point) that wizards and muggles would 
have to intermarry: science tells us that 'racial purity' is a 
euphemism for inbreeding -- just compare the genetic hardiness of the 
Weasleys to the pallid purebred Malfoys or Crouches! So what if 
Riddle's Slytherin heritage was not through his witch mother, but 
through his 'rich, snobbish and rude' paternal line? Say, for 
instance, that the wizarding gene went dormant at some point and an 
embittered squib Slytherin renounced the wizarding world forever... 
It could happen!
