You make a great point, but that is an erroneous use of the term genetic. If homosexuality is inherited, it is better termed a multifactoral type inheritance. This is also the case with conditions like cleft lip and palate. They occur less that 1% of the time in general population, but occur at a rate of 5-10% in families with a prior history. That is about the same pattern seen with homosexuality. The word genetic technically means inheritance linked to a specific gene or group of genes and follows a pattern of inheritance predictable by the chromosomes on which it resides (sex-link or autosomal). Blonds will keep popping up no matter what we do to stop them.
I have no plans on stopping them :)
I agree with you though, I was thinking about that recently while studying genetic algotrithms (which are pretty cool). So gays are either 'genetic' anomalies or they just like being gay and it has nothing to do with genetics at all. I don't care either way but I was just wondering :) Thanks for the post!
