Landmark gay ruling may put Bush in bind

"My knowledge of genetics is a bit rusty (I haven't had a biology class in four years) but even if it was a recessive gene it would eventualy be wiped out or at least decrease in instance. My point was that it isn't a genetic thing."

Not for humans. Since Humans are allowed to breed even with recessive genes that would prevent them from doing so. And there is no proof that it is or is not a genetic thing. Its all really just speculation as to what causes it.
