Thanks for the explanation, Nadia. You needn't have though, as Mendel's Laws are a specialty of mine.
I, too, tend to believe that the wizard genotype is based on more than just one pair of alleles. If it were as easy as one allel, there would be no Muggle-borns or Squibs. But unless Rowling herself explains how that system works, we're traipsing in the dark here.Originally Posted by Inverarity
Regardless, thank you, to both of you, for the help.
