After smoking and reflecting: Could it be that instead of a gene "causing" homosexuality, perhaps it is more how the child develops in the womb. What I'm saying is, we all start as women essentially, and the introduction of the Y chromosome causes the fetus to become male. (I just want to say that this realization came from watching Dodgeball and porn. Just throwin' out how my mind works.) But if the sex of the fetus is somewhat askew or imbalanced, i.e. the balance of estrogen and testosterone maybe, perhaps that could account for the child becoming a homosexual. Many gay women are for lack of a better term, butch. Some masculine characteristic or trait must be peresent already. Except for reproductive organs, it is possible to change a person's complete sexual appearance with hormone treatment (Thank you Law and Order: SVU),so this notion can't be completely offbase. Anyways, if this is right, do we say it is already the nature of the child, or how the fetus is nurtured in the womb? Perhaps I'll delve deeper into how the fetus develops in the womb and how the mother can affect the child.
