My father is a very qualified geneticist of over 30 years. He has a PHD, tenor, oversees several lab heads in the genetics department at a major pharmaseutical company, etc.

His opinion of the subject of the genetic basis of homosexuality is that there are genetic factors, but certainly no one or even few genes that determines whether someone is homosexual.

Even fruit flys can display homosexual behavior, and this is triggered from genetic alterations that vary GREATLY. In other words, there are many many sets of genes that can be altered in many ways to achieve this effect, and with an environment trigger (such as a specific change in the food given to the flys) the flies will nearly always show homosexual behavior. To clarify, they basically lose interest in the female flies and mating, even though they are capable of reproduction.

Despite being vastly more complex organisms, we are very similar to fruit flys on a genetic level. Like for most traits, a huge number of genes and alleles influence whether a person will have homosexual tendencies. No one is born gay in the sense that they are always going to be attracted to men and not women. It is more of a genetic predisposition towards it based upon a number of genes, and is still largely determined and "decided", if you will, by environmental factors.

This is a pretty general interpretation without many facts, and you can't draw many conclusions from it. If people are interested I can ask my dad for more information on the subject. I haven't gotten any further in genetics than AP Biology and the occasional slide show he has shown me, heh.

and f the mod who gave me a star for my comment. Slightly more deserved than my first star, for posting "should poker be included on a college application" in OOT instead of "The Dorm", but still pretty dumb.
