  • Ignoring the biological basis for homosexuality at the moment, changing the frequency of any gene within the human population is hard. We have long generation times, and any effort to change the frequency of a single gene is going to take longer than any policy is going to be in force.

    Radically changes are possible, say resistance to plague, as anyone sensitive dies- pretty quickly, but deliberately killing millions isn't politically acceptable.

    A confounding problem is that mutation is constantly drip feeding new genes into the population, and you can't do anything to stop that from happening.

    Changing gene frequencies takes a lot of generations: easy with bacteria; possible with dogs and other (short generation time) domesticated plants and animals; hard with humans. Tampering directly at the genetic level is theoretically possible, but again it's politically unpalatable.

    IAAPG: I am a population geneticist.
