OK. So what about over population is causing this?

OK that makes sense. But wouldn't that mean that she has to be super fertile for it to happen. So in the instance above, the girl has to produce more than twice the average amount for the gene to spread.

If the mother and daughter poses that gene why aren't they behaving like gays the way the son is?

But how does the gene pass on if gay people can't reproduce? And with the acceptance of gay marriages, gay people aren't pressured to reproduce with the opposite sex. Unless you're telling me that adoption among gay people are actually rare and they get a third party involved. I still don't understand how the gay gene is being naturally selected over the non-gay gene.

Screw those sensitive butt hurts. And yes, being fat has increased risk of heart diseases. Which doesn't only hurt yourself but the people who care for you.
