I am not at all surprised to learn of research confirming what I have always felt to be the case. I have a Masters degree in Biology and have been teaching Biology and Medical Laboratory Technology for over 30 years and the concept that homosexuality could be completely genetic has never made sense to me from a biological standpoint. Up until recently when technology made it possible, a strictly gay man and lesbian woman could not produce a child together that would pass on such a gene if one were required to be gay. In order for a gene to persist in the population, it must be passed on to the offspring. If not, the gene will die out.

I do agree with other posters that some inherited traits can make a female appear more "mannish" or a male appear more feminine, but genes are only the potential of an individual. The environment to which the person with those genes is exposed plays a major role in determining the eventual outcome.

Duchenne muscular dystrophy, Tay-Sachs disease, and (until recently) cystic fibrosis, all inherited diseases, normally kill their victims before sexual maturity—or render them so incapacitated that reproduction is unthinkable — and yet they’ve persisted for millennia.
