As for homosexuality there was some talk about the "Gay" gene, however if I recall correctly the accademic who proposed that was discredited.

To make an assertion that X or Y chromosones or any of the others causes this behaviour trait needs to be backed up with evidence, so it would be helpful Arista if you could cite your sources on this one and not just resort to statements like "It's natural", that in the trade is known as handwaving and is not legitimate as a debating technique.

Finally, someone with some sense who doesn't just throw this homophobia nonsense at me.
