LGBT

which I posted a couple of weeks ago. It may help to explain biological differences in males, females, and anyone in between. Gender is not as simple as people claim it is.

Here's something interesting. Did you know that when a dairy cow has male/female twins, the female is almost invariably something called a "freemartin"? That is, she gets too many male hormones from her brother in utero, so she will not grow up to be able to breed or be a milker. She can be raised for meat, or she can go to a sanctuary.

Which makes me wonder about something else. My daughter's friend had a pair of boy/girl fraternal twins and the boy is gay. He's known since he was quite young. I've known at least two other sets of male/female twins where one of them is gay, not always the male, so does this presuppose some hormonal cross-transmission in utero, or is it the slightly more complicated business mentioned in the thread above? Because not all the boy-girl twins I know are like that. And should I re-post the thread?
