Nicky Joe wonders:
I would really like to have some explanation from JKR about the 
genetics behind all this - some Muggles can have witch/wizard kids 
and some witch/wizards can have squib kids.  Where is the logic?  
 
Arynn explains:
It's simple genetics, {exampli gratia: both of my parents have brown eyes. I have blue eyes). Because brown eyes are B/b (Brown/blue) they both have a dominant Brown and a recesive blue. I just happened to get both of their recessive genes. (b/b)
 
Maybe wizards have a similar getetic coding. W/m (wizard/muggle) and m/m (muggle squared), so even if most of the family is W/m a m/m could come along. Since we know squibs are WAY rarer than muggleborns, obviously the wizard gene is dominant. So alot of muggles must have latent Wizard genes.
