AP Biology and Game of Thrones

One random factoid that stuck with me from learning about Mendel's cross in 9th grade AP biology was that brown hair was a dominant gene to blonde hair and therefore you can make predictions like two blonde parents must have blonde children, and a parent with homozygous brown haired genes can only have brown haired children. I wondered how many TV and movie casting directors knew that fact and for years I was on the look out for that mistake. Decades passed (literally 2 decades) without thinking about it at all, and then (minor spoiler alert) that little factoid shows up as a major plot point for George R R Martin's Game of Thrones. Apparently I wasn't the only person who thought that about the implications of Mendel on fiction.
