Why Are There Gay Men? How do homosexual males have intercourse?

While feminine sex seems to be more fluid, research shows that male gayness is an inborn, unalterable, highly genetically affected trait. But given that the trait discourages the sort of intercourse that leads to procreation — that is, intercourse with ladies — and would consequently appear to thwart a unique odds of being genetically handed down towards the next generation, why are there homosexual men after all?

Place differently, why have not homosexual man genes driven by themselves extinct?

This longstanding real question is finally being answered by brand brand new and ongoing research. For quite some time, studies led by Andrea Camperio Ciani during the University of Padova in Italy yet others have discovered that moms and maternal aunts of homosexual males are apt to have much more offspring as compared to maternal family members of right males. The outcome reveal strong help for the “balancing selection theory, ” that will be fast becoming the accepted theory regarding the basis that is genetic of homosexuality.

The idea holds that exactly the rusian brides same genetic facets that creates gayness in men additionally promote fecundity (high success that is reproductive in those men’ feminine maternal loved ones. Through this trade-off, the maternal relatives’ “gay man genes, ” though these are typicallyn’t expressed as such, have a tendency to get passed away to generations to come regardless of their propensity which will make their male inheritors homosexual.

While nobody knows which genes, precisely, these could be, a minumum of one of these seems to be on the X chromosome, relating to hereditary modeling by Camperio Ciani and their peers. Males inherit just one X chromosome — the main one from their mother — and when it offers the gene that encourages gayness in men and fecundity in females, he’s probably be homosexual while their mother along with her female loved ones will likely have a lot of children.
