Is Their a Gay Gene?

CON (NO)
William Byne, M.D., Ph.D., stated in his Journal of Homosexuality article "Science and Belief: Psychobiological Research on Sexual Orientation" (1995, Vol. 28, No. 3/4, pp. 303-344):
"While some authors have speculated about the existence of 'genes for homosexuality,' genes in themselves cannot directly specify any behavior or cognitive schema. Instead, genes direct a particular pattern of RNA synthesis which in turn specifies the production of a particular protein.
There are necessarily many intervening pathways between a gene and a specific behavior and even more intervening variables between a gene and a pattern that involves both thinking and behaving."
The term 'homosexual gene' is, therefore, without meaning, unless one proposes that a particular gene, perhaps through a hormonal mechanism, organizes the brain specifically to support a homosexual orientation. 1995
