Kemper challenges the possible cheat:
>>HunterGreen, what if Lily's grandparents were Muggle/Muggle and
Muggle/Squib? Would you still feel cheated that Lily isn't
Muggleborn, even though none of the grandparents are witch/wizards?<<

HunterGreen:
Probably not. I assume that the Evans (or Mrs. Evans' family) have a 
magical relative *somewhere* along the line, since magical genes have 
some relation to actual genes. 

>>I also encourage you to change your theory from Dudley to Petunia as
the late bloomer. It would mean more to character development that
Petunia use that which she most abhors (magic) to save that which she
loves most (Dudley... and maybe Vernon.)<<

Oh, don't worry, I already favor Petunia as the late bloomer. Dudley 
would be far less interesting (I can't see him being any more than a 
Crabbe or Goyle like wizard, one who has *some* magic, but still uses 
fists more than a wand). I was just referring to Dudley's name being 
a play on the word 'dud', since he certainly can't be a dud unless he 
was *expected* to be a magical baby. 

Here's a question though (and I just realized that this thread has 
nothing to do with the subject line any more), if a muggle and a 
muggleborn (or pureblood, I suppose), have a baby and that baby isn't 
magical, is that baby a squib or a muggle? Are wizarding genes 
expected to prevail 100% over muggle genes, or is there a 50/50 shot? 
(this might be one of those unanswerable questions)
