[–] wit@lemmy.world [S] 2 points 2 years ago* (1 child) Homosexuality is thought to be linked to higher fecundity of all the female relatives. Do you have any source for this? I have never heard about this before.. permalink fedilink source parent hideshow 2 child comments replies: [–] The_v@lemmy.world 2 points 2 years ago From a population genetics standpoint, the amount of homosexuality around is a puzzle. Because homosexual individuals have negative fitness (aka they don't make many babies), they should be very rare if it's genetically linked. There has to be a counter-benefit to the genetic family to maintain them in the population. Why it's important: If there is no counter-benefit, then homosexuality logically has no significant genetic component. It's all environmentally influenced.
