Leave it to the hard-core geeks to pick out the details of a beloved story and dissect them into oblivion.  Even the least significant elements of a book become fodder for deep conversation, speculation and, in some cases, enraged outbursts as A and B don’t seem to add up to make C.

On of these rage-debates concerns the genetic lines of wizards in J.K. Rowling’s Harry Potter world.  J.K. Rowling, to answer fans’ questions, stated that the genes that bestow magical ability are dominant.  Those with more mouth than knowledge of genetics took offense to this and decided to make their dissatisfaction known.

The truth of the matter lies deeper than a grade-school understanding of how genetics work, however.  One devoted fan (and apparent amateur geneticist), Andrea Klenotiz wrote six pages of explanation concerning why Rowling happens to be right.  Her overall conclusion?

Magical ability could be explained by a single autosomal dominant gene if it is caused by an expansion of trinucleotide repeats with non-Mendelian ratios of inheritance.

Umm… okay.  I took a semester of genetics when I was at University, but this is a bit beyond me.  If you happen to have a taste for these things, you can read the entire explanation here.


Thanks to the folks at CinemaBlend for letting us know that this important debate has finally been settled.
