If there is heritability, or some genetic factor associated with sexual orientation, you would expect this to be a dramatic reduction in same-sex couples where adoption becomes much more common and... Or not having children at all. It's not to say that gay people are infertile and won't be able to reproduce if they want to, but I think that it will simply be less common now that they don't have to. So it would be funny if there is like a drastic increase in lesbianism, because lesbian couples both decide to have a baby. That might actually make them genetically just take over the world. You only need to recruit one person. We can go to David D.
