Homosexuality has not yet been proven to be inborn.

•   The hypothalamus may be different in gays. (LeVay) But behavior can affect brain structure, as Dr. Lewis Baxter of UCLA points out. (Dallas [1996] 112)
•   Twin studies show that in a statistically significant proportion of twins where one is homosexual, so is the other. (Bailey and Pillard) But the twins were not raised apart, and the question remains why it wasn't 100% if it were genetic.
•   Chromosomes may contribute to gayness. (Hamer)

Both the Bailey & Pillard study, according to (King and McDonald), and the Hamer study, according to George Ebers ("Gay Genes Revisited") were contradicted when replicated.

If someday, a case for a genetic factor is scientifically established, it will still be little different from a genetic factor in alcoholism. That itself, as gay theologian Pim Pronk says in his dissertation, will still not take us from what is to what ought to be. (Pronk)
