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

The study of nearly a half ln people clos the door on the bate around the existence of a so-lled “gay gene. In s stead, the report fds that human DNA nnot predict who is gay or heterosexual. 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.

WHY ARE PEOPLE GAY? GAY BY CHOICE OR IS BEG GAY GEIC?

Sanrs llaborated wh Bailey on those earlier studi and said their work had always admted that there was no sgle “gay gene.

The rearchers had members of the same-sex muny review the study’s sign and language, and they adm that their termology and fns for gay, lbian and heterosexual do not reflect the full nature of the sexualy ntuum. “[Our study] unrsr an important role for the environment shapg human sexual behavr and perhaps most importantly there is no sgle gay gene but rather the ntributn of many small geic effects sttered across the genome, ” Neale said.

Estimat as to the number of gay people the populatn range om 1--20 to 1--10, so why are some people gay? In other words, 5-10% of people experience same-sex sexual attractn or behavr; of urse, this don't speak to what mak people gay. No one knows for certa why any dividual is gay, but the current thought is that beg gay is not a choice.

IS BEG GAY GEIC?

Morn science is workg to show that geics is one of the of beg gay, although some science nflicts this area. Study of fay history reveals that homosexual men have more homosexuals their fay tree than do heterosexuals.

The precise gen volved the of beg gay have not yet been intified but they appear to e om the mother.

THE 'GAY GENE' IS A MYTH BUT BEG GAY IS 'NATURAL,' SAY SCIENTISTS

Addnally, some studi have found that the bras om homosexuals differ om the bras of heterosexuals.

While psychologil factors may crease the likelihood that someone is gay, no sgle factor is known to e homosexualy. It very much appears that same-sex sexual attractn is not a choice but actg on is; so if you fe gay as the mere prence of same-sex attractn, then om everythg we unrstand, beg gay is not a choice.

IS A PERSON ‘BORN GAY’, OR IS BEG GAY A LEARNED BEHAVR?

If, on the other hand, you nsir someone to be gay only if they act on their same-sex attractn then beg gay n be nsired a choice pendg on an dividual's behavr. Whether science n ultimately prove the blogy of beg gay or not, 's important to support all adults their choic no matter how they intify. Dpe the numbers, many people still nsir homosexual behavr to be an anomalo choice.

However, blogists have documented homosexual behavr more than 450 speci, argug that same-sex behavr is not an unnatural choice, and may fact play a val role wh populatns. The 2019 study is the latt a hunt for “gay gen” that began 1993, when Dean Hamer lked male homosexualy to a sectn of the X chromosome. As the ease and affordabily of genome sequencg creased, addnal gene ndidat have emerged wh potential lks to homosexual behavr.

So-lled genome-wi associatn studi intified a gene lled SLITRK6, which is active a bra regn lled the diencephalon that differs size between people who are homosexual or heterosexual. Wh multiple gene ndidat beg lked to homosexualy, seemed highly unlikely that a sgle “gay” gene exists. In rats, manipulatn of hormon durg pregnancy produc offsprg that exhib homosexual behavr.

THERE’S NO ONE ‘GAY GENE,’ BUT GEICS ARE LKED TO SAME-SEX BEHAVR, NEW STUDY SAYS

Several hypoth have been advanced to expla how homosexualy n be beneficial perpetuatg faial gen. Gay uncl and nts, for example, are “helpers the nt” that help raise other fay members’ children to nurture the fay tree.

” For example, certa gen women help crease their fertily, but if the gen are exprsed a male, they predispose him toward homosexualy. While there is no sgle “gay gene, ” there is overwhelmg evince of a blogil basis for sexual orientatn that is programmed to the bra before birth based on a mix of geics and prenatal ndns, none of which the fet choos. So, the next time you’re a nversatn and someone says beg gay is geic, here are three thgs to remember:.

The news this week that the largt study of s kd failed to nfirm the existence of a "gay gene" is not so much a disappotment for those lookg to unrstand the LGBTQ muny, as is an acknowledgement that science do not need to tell what should be plaly obv: gays, lbians, bisexuals and pansexuals are who they are. But here's the quote that will light opponents of LGBTQ rights, some of whom sist they n "nvert" gay people to choose to be straight by prayg the gay away:. "There is no ‘gay gene’ that term whether someone has same-sex partners, ” said Ganna, who is also a geicist at the Broad Instute of MIT and Harvard as well as the Universy of Helski.
