Are you understand Why Are there any Gay Men?

While feminine sex appears to be more fluid, research shows that male gayness can be an inborn, unalterable, highly genetically affected trait. But given that the trait discourages the kind of intercourse that leads to procreation — that is, sex with ladies — and would therefore seem to thwart its very own odds of being genetically handed down towards the next generation, exactly why are there gay men at all?

Place differently, why haven’t homosexual guy genes driven by themselves extinct?

This longstanding real question is finally being answered by new and research that is ongoing. For a long time, studies led by Andrea Camperio Ciani in the University of Padova in Italy yet others are finding that moms and maternal aunts of gay males are apt to have much more offspring compared to the maternal loved ones of right guys. The outcomes reveal strong support for the “balancing selection theory,” that will be fast becoming the accepted theory of this genetic foundation of male homosexuality.

The idea holds that exactly the same hereditary facets that creates gayness in men additionally promote fecundity (high reproductive success) in those men’ female maternal family members. The maternal relatives’ “gay man genes,” though they aren’t expressed as such, tend to get passed to future generations in spite of their tendency to make their male inheritors gay through this trade-off.

While no body knows which genes, precisely, these may be, one or more of them seems to be on the X chromosome, based on hereditary modeling by Camperio Ciani along with his peers. Comente
