>>106047571>And call attention to what a basic fact being a gender is
It's a bit more complicated than poeple might think:
Scientifically speaking, there exist 3 kinds of gender, tough:
The genetic gender: XX or XY. Simple enough, right? Not always. Sometimes future mother will ovulate two eggs instead of one. Most of the time, it will result in twins, but on rare occasion, there will be case where the two eggs merge. It results with the person being born carrying two different genetic code in the same body. And if one of the egg has been fertilized by an Y spermatozoa and the other by an X one, you have an hermaphrodite that might develop both male and female features.
The reproductive organ gender: usually having XX chromosomes will result in having Female and the XY ones will result in male one, but not always. But biology is in no way a perfectly predictable machine and there will be cases where someone having XX will have male organ and someone having XY will have female organ. Add to that case of hermaphordism that can also occur with only having One set of genetic code. A side note, but when people mention their sexual orientation (which is not the same thing than gender), when they mention the gender they feel attracted to, they usually are talking abou the gender of the reproductive organs.
The brain gender: Physiological and other working characteristic difference have been noticed between the Male and the female brain. There is a lot of overlap and variables but there is also more extreme case, with people having "very female" and "very male" brain. If they happens to have the corespondent set of genital this isn't really a problem, but if they have the wrong one... Study have showed that Transsexuals tend to have brain that display characteristic of the gender opposite to the one of their reproductive organs. They are literally people with a brain in the wrong body.
That is what gender is.
