lamont:Genes don't have to procreate to survive.
I think I didn't express myself properly. I never meant to suggest that a gene had to enhance survival or reproduciton of an organism inorder for that gene to survive within a population - the thousands of detrimental genes that we have are proof against that.
What I was trying to point out is that homosexuality appears to have a genetic base, and is very common in the human populaiton - far more common then many benificial traits. This suggests a positive selection for homosexuality, which suggests there is some benifit to it. This benifit is obviously not via reproduciton, seeing as homosexuals rarely have children.
If homosexuality were purely detrimental to our population we should see a decrease in the frequency of it; a decrease to a level simular to that of other detrimental genes. We do not see this decrease. This essentially leaves 2 possibilities:
1) Homosexuality has no significant benifit or cost, and the current levels are purely a product of random genetic drift, or
2) Homosexuality has some benifit, and has been positivly selected to the current levels.
