My point was that you can pass on the gay gene without being gay yourself. I guess you and I are saying the same thing?
Well, first of all, birdie boy, there is no proven "gay gene" and it is frankly extremely unlikely. Complex behaviors, and sexual behavior definitely falls into that category, are not single gene traits. Most likely sexual orientation is due to a combination of genes, possibly fetal environment, etc. At this point no one knows. (I happen to be a biologist, BTW.)
You are correct in the general case in that a person (or other organism, of course) can pass on a trait that he/she does not carry. For example I am the blue eyed child of two brown eyed parents. Assuming my mama did not stray, both of my parents carried a recessive gene that I happened to get two copies of. Neither my brother nor my sister did. Same with any recessive.
This is not "gay genocide" since gays and lesbians have plenty of ways of reproducing ourselves, including private arrangements, it is pandering to unscientific bigotry.
I used to be lab coordinator at a sperm bank, the first to provide service to single women and lesbians. We had no "gay ban" but we did test for HIV, syphilis and hepatitis and quarantine all sperm for 6 months. There were no cases of disease transmission although gay men were welcome as donors.
As to whether any of the offspring are disproportionately gay/lesbian/bi/trans, it's may be too early to tell. The oldest would be barely into their early teens. But studies of the "standard" biological children of gay men and lesbians show that the percentage who are gay/lesbian is not different from the general population. Although the straight kids raised by gay/lesbian parents are more gay friendly than many of their peers.
