actors other than genetics have much more impact, and homosexuality is not "hard-wired" or inevitable in anybody.
A '''gay gene''' which causes [[homosexuality]] has not been identified. Factors other than genetics have much more impact, and homosexuality is not "hard-wired" or inevitable in anybody.
*Dr. Collins succinctly reviewed the research on homosexuality and offers the following: "An area of particularly strong public interest is the genetic basis of homosexuality. Evidence from twin studies does in fact support the conclusion that heritable factors play a role in male homosexuality. However, the likelihood that the identical twin of a homosexual male will also be gay is about 20% (compared with 2-4 percent of males in the general population), indicating that sexual orientation is genetically influenced but not hardwired by DNA, and that whatever genes are involved represent predispositions, not predeterminations."
