Another thing I wanted to mention... let's not forget about gay WOMEN. While it is more unlikely for a gay man to ejaculate in a women, heterosexuality is not a prerequesit for a gay woman to become fertelized by a straight man.

it is very likely that, if homosexuality is a gene, it is passed down on the women's side. It could even be that the gay gene does not lie in the DNA within our chromosomes, but the DNA within our mitochonrdira, part of every one of our cells.

Any Genetics class will tell you that Mitochondria DNA is only handed down from the women's side. While both men and women possess it, every single person on this planet ONLY has the mitochondria DNA passed down from their mother. This is because, the mitochondria DNA in a a father's sperm lies within the tail, which breaks off from the head of the sperm after fertilziation. Therefor, the only inherited Mitochondria DNA any of us have are from our mother, which was in the egg, since our fathers Mitochondria DNA (passed down from HIS mother) was lost in fertilzation when the tail broke off.

Im sorry if it seems like this one is rambled, I have to go to work and I wanted to get this down before I lost my train of thought.
