So they are genetically identical yet one is gay and the other is not? This is anecdotal evidence of course but leads me to the opposite conclusion you're drawing. Obviously, in this case at least, the cause is not genetic. Lessening the chance that he was born that way. Then again there could be some difference in their development in the womb. Interesting.
