WHY ARE THERE GAY MEN?
New rearch shows the gen that make men gay appear to make their mothers and nts more reproductively succsful. * one gay men *
While female sexualy appears to be more fluid, rearch suggts that male gayns is an born, unalterable, strongly geilly fluenced tra.
HOW MANY PEOPLE ARE LBIAN, GAY, BISEXUAL, AND TRANSGENR?
* one gay men *
But nsirg that the tra disurag the type of sex that leads to procreatn — that is, sex wh women — and would therefore seem to thwart s own chanc of beg geilly passed on to the next generatn, why are there gay men at all?
Put differently, why haven't gay man gen driven themselv extct?
For several years, studi led by Andrea Camper Ciani at the Universy of Padova Italy and others have found that mothers and maternal nts of gay men tend to have signifintly more offsprg than the maternal relativ of straight men. The rults show strong support for the "balancg selectn hypothis, " which is fast beg the accepted theory of the geic basis of male theory holds that the same geic factors that duce gayns mal also promote fecundy (high reproductive succs) those mal' female maternal relativ.

Through this tra-off, the maternal relativ' "gay man gen, " though they aren't exprsed as such, tend to get passed to future generatns spe of their tenncy to make their male herors no one knows which gen, exactly, the might be, at least one of them appears to be loted on the X chromosome, acrdg to geic molg by Camper Ciani and his lleagu. Mal her only one X chromosome — the one om their mother — and if clus the gene that promot gayns mal and fecundy femal, he is likely to be gay while his mom and her female relativ are likely to have lots of kids.
If a dghter hers that same X-lked gene, she herself may not be gay, but she n pass on to her sons. [Why Are There Gay Women? ]But how might the "gay man gene" make femal more reproductively succsful?
