Squibs have genes to do magic?

CH3ed:
Actually JKR did write on her site that magic is a dominant gene.
"A Squib is almost the opposite of a Muggle-born wizard: he or she is 
a non-magical person born to at least one magical parent. Squibs are 
rare; magic is a dominant and resilient gene."

Jazmyn is right that Jo got it wrong (assuming wizarding genetics 
follows the same rule as in the real world). If magic is genetically 
determined, then it must be a recessive trait. 


CH3ed who doesn't fault Jo for making a boo-boo on the science. She is 
a marvelous writer nonetheless. :O)
