  • That is essentially the car version of the Sam Vimes “Boots” Theory of Socio-Economic Unfairness.

    The reason that the rich were so rich, Vimes reasoned, was because they managed to spend less money.

    Take boots, for example. He earned thirty-eight dollars a month plus allowances. A really good pair of leather boots cost fifty dollars. But an affordable pair of boots, which were sort of OK for a season or two and then leaked like hell when the cardboard gave out, cost about ten dollars. Those were the kind of boots Vimes always bought, and wore until the soles were so thin that he could tell where he was in Ankh-Morpork on a foggy night by the feel of the cobbles.

    But the thing was that good boots lasted for years and years. A man who could afford fifty dollars had a pair of boots that’d still be keeping his feet dry in ten years’ time, while the poor man who could only afford cheap boots would have spent a hundred dollars on boots in the same time and would still have wet feet.

  • if she were XY in this scenario, wouldn’t that mean that she’d pass that trait along to her kids as well?

    I could be wrong, but I don’t believe XY females (Swyer syndrome) produce eggs and thus cannot bear their own children.

    But a colorblind XX woman who can bear children would give birth to colorblind sons and, if the father of the child is also colorblind, colorblind daughters.

    That’s fascinating! Colorblindness in XX women is very rare! Is her father colorblind?

    As I understand it the genes for our cones comes from the X chromosome. So for women to be colorblind, their mother has to have one faulty X chromosome and their father has to be colorblind, so the woman can inherit two faulty X chromosomes.

    Whereas men just need to inherit one faulty X chromosome from their mother and the Y chromosome from their father.

    (Sorry, I’ve always been fascinated by color blindness. I had a friend in college who was quite bemused by how many questions I had for him when I learned he was colorblind.)
