"Actually, I’ve hypothesized previously that a genetic defect of this variety would be natures response to “cull the herd” and basically reduce the numbers of the species with such a genetic anomaly."

That presupposes that "nature" is some sort of conscious mind that is capable of making such a "decision." But if "nature" wanted to "cull the herd", why wouldn't nature develop a more efficient means of reducing the population than simply making 2-3% of the population homosexual? Wouldn't plagues be a much more efficient way of culling the herd?

There is no such predisposition that necessitates a conscious mind to make such a decision. A defective genome that predisposes an individual to behave in such a manner that would make the propagation of it’s genetic line is a possibility, but not one that must be dictated by an intelligent guiding hand.

In the end, such a hypothesis (mine) is idle speculation, and really has nothing to back it up.
