Turns out, the moms and aunts of gay men have an advantage over the moms and aunts of straight men for several reasons: They are more fertile, displaying fewer gynecological disorders or complications during pregnancy; they are more extroverted, as well as funnier, happier and more relaxed; and they have fewer family problems and social anxieties.

But as for why genetic factors would exist that make men gay, it appears that these genes make women, as well as gay men, alluring to other men. The results show strong support for the "balancing selection hypothesis," which is fast becoming the accepted theory of the genetic basis of male homosexuality.

Previously, the Italian researchers suggested that the "gay man gene" might simply increase androphilia, or attraction to men, thereby making the males who possess the gene homosexual and the females who possess it more promiscuous.

For several years, studies led by Andrea Camperio Ciani at the University of Padova in Italy and others have found that mothers and maternal aunts of gay men tend to have significantly more offspring than the maternal relatives of straight men. Wir haben Schwule gefragt, wie ihr „Gaydar" funktioniert und welche Anzeichen es gibt.

A new study by Camperio Ciani and his team addresses the question for the first time. Sign up to our newsletter Newsletter.

Attracting and choosing from the best males enables these women to produce more offspring, he noted. Dein Guide für ein stilvolles und erfülltes Leben!.

While female sexuality appears to be more fluid, research suggests that male gayness is an inborn, unalterable, strongly genetically influenced trait.

While no one knows which genes, exactly, these might be, at least one of them appears to be located on the X chromosome, according to genetic modeling by Camperio Ciani and his colleagues. The theory holds that the same genetic factors that induce gayness in males also promote fecundity high reproductive success in those males' female maternal relatives.

Along with the staff of Quanta, Wolchover won the Pulitzer Prize for explanatory writing for her work on the building of the James Webb Space Telescope. Natalie Wolchover was a staff writer for Live Science from to and is currently a senior physics writer and editor for Quanta Magazine.

But how might the "gay man gene" make females more reproductively successful? Männerpaar bei Modern Family Ist die Gay-Community manchmal zu selbstkritisch? Through this trade-off, 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.

Males inherit only one X chromosome — the one from their mother — and if it includes the gene that promotes gayness in males and fecundity in females, he is likely to be gay while his mom and her female relatives are likely to have lots of kids. This longstanding question is finally being answered by new and ongoing research.

But a likeable encounter in the elevator changes everything. Rather than making women more attracted to men, the "gay man gene" appears to make these women more attractive to men. If a daughter inherits that same X-linked gene, she herself may not be gay, but she can pass it on to her sons.
