WHY ARE THERE GAY MEN?
New rearch shows the gen that make men gay appear to make their mothers and nts more reproductively succsful. * what makes guys gay *
While female sexualy appears to be more fluid, rearch suggts that male gayns is an born, unalterable, strongly geilly fluenced tra. 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?
WHY ARE PEOPLE GAY? GAY BY CHOICE OR IS BEG GAY GEIC?
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?
WHAT SCIENCE KNOWS ABOUT WHY PEOPLE ARE GAY
]But how might the "gay man gene" make femal more reproductively succsful? Prevly, the Italian rearchers suggted that the "gay man gene" might simply crease androphilia, or attractn to men, thereby makg the mal who posss the gene homosexual and the femal who posss more promiscuo. But after vtigatg the characteristics of 161 female maternal relativ of homosexual and heterosexual men, the rearchers have adjted their hypothis.
Rather than makg women more attracted to men, the "gay man gene" appears to make the women more attractive to men. The androphilic pattern that we found is about femal who crease their reproductive value to attract the bt mal, " Camper Ciani told Life's Ltle out, the moms and nts of gay men have an advantage over the moms and nts of straight men for several reasons: They are more fertile, displayg fewer gynelogil disorrs or plitns durg pregnancy; they are more extroverted, as well as funnier, happier and more relaxed; and they have fewer fay problems and social anxieti. "It is que possible that there are several fluenc on formg a homosexual orientatn, " said Gelf Rieger, a sexual orientatn rearcher at Cornell Universy.
But as for why geic factors would exist that make men gay, appears that the gen make women, as well as gay men, allurg to other men. Scientists may have fally solved the puzzle of what mak a person gay, and how is passed om parents to their children.A group of scientists suggted Tuday that homosexuals get that tra om their oppose-sex parents: A lbian will almost always get the tra om her father, while a gay man will get the tra om his mother.The heredary lk of homosexualy has long been tablished, but scientists knew was not a strictly geic lk, bee there are many pairs of intil tws who have differg sexuali.
HOW TO KNOW IF YOU ARE GAY
Scientists om the Natnal Instute for Mathematil and Blogil Synthis say homosexualy seems to have an epigeic, not a geic lk.Long thought to have some sort of heredary lk, a group of scientists suggted Tuday that homosexualy is lked to epi-marks — extra layers of rmatn that ntrol how certa gen are exprsed.
In homosexuals, the epi-marks aren't erased — they're passed om father-to-dghter or mother-to-son, explas William Rice, an evolutnary blogist at the Universy of California Santa Barbara and lead thor of the study."There is pellg evince that epi-marks ntribute to both the siary and dissiary of fay members, and n therefore feasibly ntribute to the observed faial herance of homosexualy and s low nrdance between [intil] tws," Rice not.Rice and his team created a mathematil mol that explas why homosexualy is passed through epi-marks, not geics. Evolutnarily speakg, if homosexualy was solely a geic tra, scientists would expect the tra to eventually disappear bee homosexuals wouldn't be expected to reproduce. But bee the epi-marks provi an evolutnary advantage for the parents of homosexuals: They protect fathers of homosexuals om unrexposure to ttosterone and mothers of homosexuals om overexposure to ttosterone while they are gtatn."The epi-marks protect fathers and mothers om excs or unrexposure to ttosterone — when they rry over to oppose-sex offsprg, n e the masculizatn of femal or the femizatn of mal," Rice says, which n lead to a child beg gay.
SCIENTISTS REVEAL WHAT MAK A MAN GAY
Rice not that the markers are "highly variable" and that only strong epi-marks will rult a homosexual offsprg.Though scientists have long spected some sort of geic lk, Rice says studi attemptg to expla why people are gay have been few and far between."Most mastream blogists have shied away om studyg bee of the social stigma," he says. Well there are many exampl of homosexualy nature, 's very mon." Homosexual behavr has been observed black swans, pengus, sheep, and other animals, he says.Rice's mol still needs to be tted on real-life parent-offsprg pairs, but he says this epigeic lk mak more sense than any other explanatn, and that his team has mapped out a way for other scientists to tt their work."We've found a story that looks really good," he says.
Estimat as to the number of gay people the populatn range om 1--20 to 1--10, so why are some people gay? Are they gay by choice or is beg gay geic?
