The research, which analyzed data on DNA and sexual experiences from almost half a million people, found there are thousands of genetic variants linked to same-sex sexual behavior, most with very small effects.įive of the genetic markers were “significantly” associated with same-sex behavior, the researchers said, but even these are far from being predictive of a person’s sexual preferences. A new comprehensive scientific study of the biological roots of sexual orientation released Thursday proved that there no “gay gene” and that genetic factors are insignificant in determining sexual orientation. So, what happens when science proves that homosexuals aren’t “born that way”? Perhaps we’ll find out.
