It mostly works for women and not at all for men. It's a process innate to the zygote and all humans. Somehow, nature leaps out of the bushes and tries to suppress the bad genes on the X chromosome. With girls there is a redundant X chromosome. Guys get a Y instead of 2 Xs. So, yes, girls are really born with two strikes against them. I delve into history in the late night. I'm fascinated by it. I was looking tonight on a dark subject that my reference to time travel brought back.
The distant progeny of Queen Victoria were a maelstrom of disfunction on the male side. On the female side, not so much. In another century that saw the brutal extinction of a hundred million people in the name of various isms, I do miss these girls.
On balance and historically not much was made of the princesses. They mostly vanished. On the other hand, I would have liked to have seen the Angevin World of Lord Darcy and any one of those girls was easily a hundred times brighter and smarter than Kamela.
Yeah yeah, they had bad genes, that's for another post.
