Genetic variants underlying male bisexual behavior, risk-taking linked to more children, study shows

Because same-sex sexual behavior does not result in offspring, evolutionary biologists have long wondered how the genes associated with this behavior have persisted in the human genome, and whether they will remain in the future. A new study suggests that part of the explanation -- specifically for male bisexuals -- has to do with risk-taking behavior.
