From John Earney:

Re: A function for “gay genes” after all? (Feb. 8): Good article with some good points. A point that I would like to make: homosexuality occurs in animals. In sheep for instance some rams will not mate ewes but will ride other rams. Why? Most cases are well bred purebreds that have a high inbred factor. Brother sister mating or maybe son over mother within a already narrow gene base flock.

Is this not natures way to avoid further inbreeding? Samoa is an island; the same scenario should apply.
