Sexual Orientation Determined by Genes

[migrendel]

I wouldn't be too influenced by this study. I imagine that Drosophila malenagater was chosen because it has such a simple genome and reproduces so quickly. Obviously, human behaviors are determined by something much more involved.

However, I did read an interesting Swedish study. It showed that sexual preference was related to a hypothalmic structure which detected certain pheromones. The study concluded that men who are attracted to other men have the same hypothalmic function in this area as women. Naturally, much more research is needed on this point, but I think it is a far more viable lead than this fruit fly study.
