 JK knows NOTHING about genetics.  You can not have 'mudbloods' if its a 
 dominant gene.  Its got to be a recessive gene if you can have two 
 muggles produce a wizard.  Genetics was my area in college, so I know 
 what I am talking about here.

 JK's idea simply does not work.  If Wizard genes were always dominant, 
 there would be NO squibs born to purebred families.

 Aha!  I don't know as much as you do about genetics, but I'd always thought that something just didn't seem right.
 Perhaps, then, the magic gene is kind of...well, a "rogue", as it were?  Perhaps it isn't subject to the normal laws of genetics?
