NO SGLE ‘GAY GENE’ TERM SAME-SEX SEXUAL BEHAVR, DNA ANALYSIS FDS

A new study that analyzed the DNA of nearly half a ln people has found that, while geic differenc play a signifint role sexual behavr, there is no sgle gene fdgs, which looked at behavr and not sexual inty, bunk the notn of a sgular “gay gene.

WHAT DO THE NEW ‘GAY GEN’ TELL ABOUT SEXUAL ORIENTATN?

“This new study provis even more evince that that beg gay or lbian is a natural part of human life, a ncln that has been drawn by rearchers and scientists time and aga, ” GLAAD Chief Programs Officer Zeke Stok said a statement. The work “also renfirms the long-tablished unrstandg that there is no nclive gree to which nature or nurture fluence how a gay or lbian person behav. “There is no gay gene, ” Ganna said, “but rather non-heterosexualy is fluenced by many ty-effect geic factors.

Some people who have had sex wh a same-sex partner don’t nsir themselv gay and aren’t exclively attracted to people of the same sex, Bailey says. Men the new study who said they have had same-sex partners, tend to be more exclively homosexual than women were, Ganna and lleagu found. Bbank dataset, for example, younger people reported havg same-sex partners more often than olr people did, probably bee homosexual activy was illegal the Uned Kgdom until 1967.

In the new study, the more exclively homosexual partners men had, the fewer children they had; up to 80 percent fewer children than heterosexual men. Diamond disagre that rearchers need to fd a mechanism to expla the persistence of geic variants lked to homosexualy.

THERE IS NO ‘GAY GENE.’ THERE IS NO ‘STRAIGHT GENE.’ SEXUALY IS JT PLEX, STUDY NFIRMS

Homosexualy isn't a liftyle choice, but is rooted a person's blogy, acrdg to a ntroversial new study.

Rearch om NorthShore Universy Illois claims to have found geic markers that n reveal if a man is gay. Scientists looked at the DNA of more than 2, 000 people and loted two regns of chromosom that may be lked to study has been scribed as 'weak' by pennt scientists, and the study's thors adm the lk is 'speculative' say, however, that the rearch uld help them get closer to fdg so-lled 'gay gen'.

SCIENTISTS FD DNA DIFFERENC BETWEEN GAY MEN AND THEIR STRAIGHT TW BROTHERS

Scroll down for vio Gay men share variatns their DNA that may pot to clu about how sexual orientatn is hardwired to our geic , acrdg to new rearch. The latt study is unlikely to settle this bate, but is by no means the first to try and the claim that homosexual men share a ‘gay gene’ created a furore the 1993, Amerin geicist Dean Hamer found fai wh several gay mal on the mother’s si, suggtg a gene on the X chromosome. He showed that pairs of brothers who were openly gay shared a small regn at the tip of the X, and proposed that ntaed a gene that predispos a male to homosexualy.

In the latt study rearchers at NorthShore Universy (NSU) HealthSystem’s Rearch Instute, based  Evanston, ma the fdgs after nductg a genome-wi associatn study (GWAS) examed the sexual orientatn of 1, 077 homosexual and 1, 231 heterosexual orientatn of participants the study was rated based on their self-reported sexual inty and sexual were asked to provi DNA by blood or saliva sampl that were then analysed for variatns their geic . 'This is particularly so for tras like beg gay that are likely to volve many gen and where "environmental" fluenc, perhaps both utero and postnatally, n have a strong effect. 'The new data on geic associatns they report here do not show sufficient statistil signifince to make any formal lk between a gene or chromosome regn and beg gay or heterosexual.

He was challenged at every turn by people unwillg to accept that homosexualy is at least partly geic, rather than a ‘liftyle choice’.

More recently, Febary 2014, scientists announced they had found two stretch of DNA lked to homosexualy the study, Chigo Universy rearchers analysed the DNA of more than 400 pairs of gay brothers, reced at Gay Pri ftivals at march over several flagged up two piec of DNA that seem to be lked to October 2015, experts claimed they uld predict whether someone is gay or straight wh up to 70 per cent accuracy by lookg at their study volved 37 pairs of tws which one brother was homosexual and the other heterosexual, and 10 pairs which both were a puter program lled Fuzzy Fort they found that ne small regns of the geic played the key role on cidg whether someone is heterosexual or homosexual. We have known for s that sexual orientatn is partly herable men, thanks to studi of fai which some people are straight and some people are gay.

In 1993, geic variatns a regn on the X chromosome men were lked to whether they were heterosexual or homosexual, and 1995, a regn on chromosome 8 was intified.

Alan Sanrs at North Shore Universy, Illois, and his team ppoted the gen by parg DNA om 1077 gay and 1231 straight men.

“There will be men who have the form of gene that creas the chance of beg gay, but they won’t be gay. There have been studi suggtg that there is a geic element to homosexualy women, but more rearch has been done men, says Sanrs.

The latt fdgs open the prospect to intifyg the whole pathway of gen volved both homosexual and heterosexual orientatn, says Dean Hamer at the US Natnal Instut of Health, who led the study that ppoted chromosome X back 1993. The study of nearly a half ln people clos the door on the bate around the existence of a so-lled “gay gene. It is worth keepg md that this study only vers some typ of sexualy — gay, lbian and cis-straight — but don’t offer many sights to genr inty.

Humans have tried to unrstand human sexualy for centuri — and geics rearchers joed the ay the early 1990s after a seri of studi on tws suggted homosexualy ran fai.

“As a teenager tryg to unrstand myself and unrstand my sexualy, I looked at the ter for “the gay gene” and obvly me across Xq28, ” said Fah Sathirapongsasuti, a study -thor and senr scientist at 23andMe, which he joked once led him to believe he hered his gayns om his mother. “We worried a lot about volunteer bias, ” said Bailey, whose rearch clus a wily publicized study on Xq28 and gay brothers om 2018. Sanrs llaborated wh Bailey on those earlier studi and said their work had always admted that there was no sgle “gay gene.
