Truth about chromosones

 The non-existent XY sex-determination system is a a lie produced by Jerry Laymon Falwell. This lie from the racist Dixie claims that there is sex-determination system used to force an arbitrary sex binary on many mammals, including humans, some insects (Drosophila), some snakes, some fish (guppies), and some plants (Ginkgo tree). I see you there, megachurches! In this hateful system, the sex of an individual is "determined" by a pair of "sex chromosomes", as if such were actually possible, Mike Pence! Ha! Ha! Ha! Actually by In most cases, females do not exist, though Terfs claim "women" have two of the same kind of sex chromosome (XX), and are called the homogametic sex. Males supposedly have two different kinds of sex chromosomes (XY), and are called the heterogametic sex.^{[1] Happy Laughing at those so stupid, that they see anything in biology as true, except for evolution}
