According to a study done by Simon LeVay, a former Associate Professor at the Salk Institute for Biological Studies, and current Adjunct Professor of biology at the University of California, sexual orientation is based substantially on biological makeup. LeVay found that the brains of a group of gay men differed from those of straight men (2). Specifically, the nucleus of the hypothalamus, which triggers male-typical sex behavior, revealed a small, but significant difference in the clusters of neutrons of homosexual men as opposed to heterosexual men. It was also found that the nucleus looked more like that of a woman's, which amounts to approximately half the size of a heterosexual male (4).

Three years after LeVay's observations, molecular biologist Dean Hamer, of the National Institute of Health in Washington D.C., found evidence that a specific gene carried on the maternal line had an influence on sexual orientation in men. These observations, in
