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.

NO ‘GAY GENE’: MASSIVE STUDY HOM ON GEIC BASIS OF HUMAN SEXUALY

In s stead, the report fds that human DNA nnot predict who is gay or heterosexual.

THERE’S (STILL) NO 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.

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

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. In other words, tri to judge if a person leans gay, straight or bisexual. “[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.

IS THERE A "GAY GENE"? MAJOR NEW STUDY SAYS NO

“There is no ‘gay gene’, ” says lead study thor Andrea Ganna, a geicist at the Broad Instute of MIT and Harvard Cambridge, and his lleagu also ed the analysis to timate that up to 25% of sexual behavur n be explaed by geics, wh the rt fluenced by environmental and cultural factors — a figure siar to the fdgs of smaller studi.

There is no one gene for beg gay, and though gen seem to play a role termg sexual orientatn and same-sex behavr, ’s small, plex, and anythg but termistic. “There is no sgle gay gene, but rather the ntributn of many small geic effects sttered across the genome, ” he emphasized. “We know that smell has a strong tie to sexual attractn, but s lks to sexual behavrs are not clear, ” said -thor Andrea Ganna, an stctor at HMS and Massachetts General Hospal om the Instute for Molecular Medice study is part a rponse to gay, lbian, and bisexual people’s cursy about themselv, said Fah Sathirapongsasuti, a senr scientist at 23andMe and -thor on the study, who is himself gay.

Sathirapongsasuti wasn’t the only one lookg to the putative “gay gene” for self-unrstandg or validatn. Michael Bronski, profsor of the practice media and activism wh the mtee on studi of women, genr, and sexualy, and thor of A Queer History of the Uned Stat, says the allure of a “gay gene” grew om the flourishg gay-rights movement the after the Stonewall rts 1969. Conservative opponents of the movement claimed that “homosexual acts are a choice, people choose to m them, or people are sced to the gay liftyle, ” he explas.

NO SGLE GENE ASSOCIATED WH BEG GAY

’77, then a rearcher at the Natnal Instut of Health, published rults showg a rrelatn between male homosexual behavr and a clter of gen, lled Xq28, at the tip of the X chromosome. Exactly which gene this clter may be volved has proven elive—the current study found no signifint associatn between the X chromosome and same-sex sexual behavr—but the ia that a “gay gene” might lie somewhere Xq28—or elsewhere—was ptivatg. Zeke Stok, chief programs officer of the LGBTQ advocy anizatn GLAAD, ncurred an emailed statement: “This new study provis even more evince 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.

”Not everyone has embraced the approach of legimizg homosexualy through geics, however. Others have warned that the search for a geic e would pathologize homosexualy the same way psychology did the twentieth century: efforts by psychoanalysts such as Irvg Bieber led to the cln of homosexualy the Amerin Psychiatric Associatn’s Diagnostic and Statistil Manual of Mental Disorrs until 1972.

As noted above, the gen that rrelated wh same-sex sexual behavr also rrelated wh willgns to take risks, a nnectn that might not hold up cultur where homosexualy is ls stigmatized and those who are ls risk tolerant would therefore feel more able to act openly. The rearchers say that, although variatns the gen nnot predict whether a person is gay, the variants may partly fluence sexual Ganna, lead thor and European Molecular Blogy Laboratory group lear at the Instute of Molecular Medice Fland, said the rearch rerc the unrstandg that same-sex sexual behavr is simply “a natural part of our diversy as a speci. Some of the variants were rrelated wh same-sex sexual behavr men, others women, and some Vila, director of the Center for Geic Medice Rearch at Children’s Natnal Health System, said the study marks the end of “the simplistic ncept of the ‘gay gene.

THERE’S NO EVINCE THAT A SGLE ‘GAY GENE’ EXISTS

For stance, rearch has shown patterns fai wh multiple men the same fay intifyg as gay.

Environmental effects may be a factor for some people; for stance, havg olr brothers creas the odds that younger brothers will be gay, which rearchers spect may have to do wh chang to the mother’s immune system rponse to the earlier Stok, chief programs officer for GLAAD, said a statement that the new rearch on the geics “provis even more evince 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. This new rearch 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's no such thg as a sgle "gay gene" that driv a person's sexual behavr, nclus the largt geic study ever nducted on the issue. "That should also support the posn that we shouldn't try and velop gay cur.

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

"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, " said GLAAD Chief Programs Officer Zeke Stok.

This new rearch 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. "This reflects voic om the LGBTQ+ (lbian, gay, bisexual, transgenr, queer+) muny argug that a range of sexuali exist, " Mills wrote. Image source, Getty ImagA geic analysis of almost half a ln people has nclud there is no sgle "gay gene" study, published Science, ed data om the UK Bbank and 23andMe, and found some geic variants associated wh same-sex geic factors acunted for, at most, 25% of same-sex behavur.

SEARCH FOR 'GAY GEN' COM UP SHORT IN LARGE NEW STUDY

Advocy group GLAAD said the study nfirmed "no nclive gree to which nature or nurture fluenced how a gay or lbian person behav. "There is no sgle gay gene, and a geic tt for if you're gog to have a same-sex relatnship is not gog to work. "Fah Sathirapongsasuti, senr scientist at 23andMe, add; "This is a natural and normal part of the variatn our speci and that should also support precisely the posn that we shouldn't try and velop gay 'curism'.

NO 'GAY GENE', BUT STUDY FDS GEIC LKS TO SEXUAL BEHAVR

"David Curtis, honorary profsor at the UCL Geics Instute, Universy College London, said: "This study clearly shows that there is no such thg as a 'gay gene'. "Even if homosexualy is not geilly termed, as this study shows, that do not mean that is not some way an nate and dispensable part of an dividual's personaly. "Zeke Stok, om the LGBT media advocy anisatn GLAAD, said: "This new rearch re-nfirms the long-tablished unrstandg that there is no nclive gree to which nature or nurture fluence how a gay or lbian person behav.

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. “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. Dpe the numbers, many people still nsir homosexual behavr to be an anomalo choice.

NO 'GAY GENE': MASSIVE STUDY HOM ON GEIC BASIS OF HUMAN SEXUALY

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. 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.

“There is no gay gene, ” Ganna said, “but rather non-heterosexualy is fluenced by many ty-effect geic factors. The new study is an advance over prev attempts to fd “gay gen, ” says J. 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.

THE 'GAY GENE' IS A TOTAL MYTH, MASSIVE STUDY CONCLUS

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. Only the last 50 years have gay people tend to exclively choose same-sex partners, she says. In an terview, she said the study is further evince that prev reports of a "gay gene" on the X chromosome are wrong.

And bee the rearchers didn't fd gene variants that rrelated wh a gradient of sexual behavr, she says, unrcuts Aled Ksey's s-old sle, which ranked people on a spectm of sexualy, om exclively heterosexual to exclively homosexual. A clear geic lk would suggt that gay people are “born this way, ” as opposed to havg ma a liftyle choice.

MANY GEN INFLUENCE SAME-SEX SEXUALY, NOT A SGLE ‘GAY GENE’

Yet some fear that such a fdg uld be mised “cure” homosexualy, and most rearch teams have shied away om tacklg the topic. They asked more than 477, 000 participants whether they had ever had sex wh someone of the same sex, and also qutns about sexual fantasi and the gree to which they intified as gay or straight. Dpe the associatns, the thors say that the geic siari still nnot show whether a given dividual is gay.
