Men with bisexual, risk-taking gene variants tend to have more kids: study

A new study from the University of Michigan (U-M) suggests that genetic variants tied to male bisexual behavior and risk-taking are linked to more offsprings. Major findings: The study, published in the journal Science Advances on Wednesday, reveals that heterosexual males who carry genetic variants related to bisexual behavior (BSB) — known as BSB-associated alleles — father more children than average. Additionally, those who describe themselves as risk-takers tend to have more kids and are more likely to carry the said genetic variants.
