(Photo credit: Wikipedia ) It is reasonable to assume that sexual behavior--in any and all of its manifestation—is directed by the activity of many, possibly hundred of genes. But the exact and specific type of sexual expression is also influenced by countless environmental forces that interact with the genes in complex ways (Hubbard, 1997; Ridley, 2003). Except for the rare physical abnormalities (such as Huntington’s Disease ) at the present time, there is no evidence of a direct causative link between a single gene and complex psycho-social behavior such as sexual preference (Collins, 2006). This is not my opinion but read any book on behavior genetics or molecular biology and the authors will unanimously agree that, at present, there is no gay gene. Lewontin et al. stated this explicitly: “Up to the present time no one has ever been able to relate any aspect of human social behavior to any par...
