““After nearly a decade of intensive hunting, what geneticists have found is not a "gay gene" but a few "gay locations." Some genes that reside in these locations are indeed tantalizing candidates as regulators of sexual behavior-but none of these candidates has been experimentally linked to homo- or heterosexuality. One gene that sits int he Xq28 region, for instance, encodes a protein that is known to regulate the testosterone receptor, a well-known mediator of sexual behavior. But whether this gene is the long-sought gay gene on Xq28 remains unknown.””
