We’ve written before on these pages about how biologists arebecoming convincedfrom their animal studies, that homosexuality is programmed into a person (especially a male) and is not a "choice."

Ker Than writes in LiveScience.com about a new study showing that a mother’s genes may affect her sons sexual orientation. Researchers studied about 100 mothers with gay sons and compared their DNA to about 100 mothers with non-gay sons.
