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

“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.

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. 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.

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

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. 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’, ” 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.

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

No dividual gene alone mak a person gay, lbian or bisexual; stead, thoands of gen likely fluence sexual orientatn, a massive new study of the genom of nearly half a ln people human societi and both sex, between 2% and 10% of people report engagg sex wh a member of the same sex, eher exclively or addn to sex wh a member of the oppose sex, the rearchers said. Related: 5 Myths About Gay People Debunked"Bee is a ntroversial topic, fundg has historilly been limed and recment of participants was difficult, " study -thor Fah Sathirapongsasuti, a senr scientist and putatnal blogist at the geic ttg pany 23andMe, told Live Science.

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. 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. 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.

Those who nsir beg gay a disadvantage life (which still is, certa societi), might regard gay people differently if they knew that beg gay was an hered tra, rather than a nsequence of life events, such as a particular type of upbrgg, or mixg wh certa sorts of iends or even a liberate cisn. It was quickly shown that, fact, the real chance of two intil tws beg gay was around 40-50 percent, whereas was ls non-intil on, though still somewhat greater than the general populatn.

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

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. "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.

While the variatns the gen are not enough to raise a rabow flag and label anyone as unqutnably gay, the rearchers say the blogil variants may at the very least partly fluence sexual behavr. This new rearch, he said “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. Geics nnot tell "the whole story, " as Eric Vila, director of the Center for Geic Medice Rearch at Children’s Natnal Health System, told the Post, about what "mak" somebody gay.

Still others, backg the same e, disurage any vtigatn to the blogil origs of sexual orientatn, fearful that posive rults will lead to attempts to rid the world of potential homosexuals.

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

For them, the disvery of how an dividual be gay is likely to shed light on how sexualy-related gen build bras, how people of any persuasn are attracted to each other, and perhaps even how homosexualy evolved. Hamer had jt published a study that claimed not only to have fally proved that male homosexualy was at least partially geic but also to have ppoted the stretch of chromosome where one of the gen volved rid.

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

Yet Hamer ntends that his rults suggt there is a lk to Xq28 and that the Rice study was biased bee one of the thors told Hamer that he didn’t believe a gay gene uld exist. Whether or not a gay gene, a set of gay gen, or some other blogil mechanism is ever found, one thg is clear: The environment a child grows up has nothg to do wh what mak most gay men gay.

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

By settg up a stand at Gay Pri paras and approachg “gay iendly” groups like PFLAG (Parents, Fai and Friends of Lbians and Gays), Sanrs has found more than 4, 000 gay men wh a brother who are terted participatg. Even if social prsur through the ag led some gay men to have some children, the signifintly lower rate of reproductn would eventually lead to the disappearance of the gene (as Hamer do note his book, The Science of Dire: The Search for the Gay Gene and the Blogy of Behavr).

Andrea Camper-Ciani, a profsor of ethology and evolutnary psychology at the Universy of Padua, terviewed 98 gay men and 100 straight men and found that the mothers of gay men had an average of 2.

In addn to lookg at how they spent their money, Rahman tried to see if gay men had some kd of extra psychologil generosy by askg qutns like, “Assumg you had a ln pounds, would you buy gifts for your fay?

THE REAL STORY ON GAY GEN

But 21st-century Wtern society, and the homosexuals there, uld be somethg of an anomaly human history, acrdg to Pl Vasey, an associate profsor of psychology at the Universy of Lethbridge Alberta.

Another problem wh kship selectn studi that look only England and, particular, the Uned Stat, is that kship ti for homosexuals might not be as strong as they would be elsewhere. “The Uned Stat is profoundly homophobic, ” says Vasey, “so you n’t be directg altism at your fay members if they’ve kicked you out and you’ve moved to the other si of the untry.

To put the kibosh on the ia that the evolutn of a gay gene prents an unsolvable nundm, Sergey Gavrilets, a theoretil evolutnary blogist at the Universy of Tennsee, veloped a mathematil mol of how a set of what he lls “sexually antagonistic” gen might evolve. ”) But he did clu Camper-Ciani’s rults and also assumed that gay gen would be passed down on the mother’s si, on the X chromosome, as dited by mol shows that over centuri an effect you might ll the homophobe’s paradox has been at work on the human genome: The more tolerant the society, the more likely is to mata gay gen.

THERE’S (STILL) NO GAY GENE

Image, for stance, that for every extra child that such a gay gene–rryg woman has, a gay man n have one fewer and the balance necsary for the survival of the gene is still mataed. ” On the other hand, the more tolerant the society, the more gay men n be ee to be who they are, so the more likely they will be childls—and the more difficult will be for any female the fay to make up for the loss.

Ivanka Savic Berglund, a nroscientist at the Karolska Instute Stockholm, put gay men, straight men, and women a PET snner (not all at the same time) and watched how their anterr hypothalam l up when prented wh an odor siar to one found men’s sweat and one siar to a scent found women’s ure.

THE LIFE OF THE GAY GENE: OM HYPOTHETIL GEIC MARKER TO SOCIAL REALY

No experiment has yet led that rearchers do prove that ttosterone n alter human sexual orientatn—gay gene or no gay gene—the possibily of preventg homosexualy will bee a realy.

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. “A lot of people want to unrstand the blogy of homosexualy, and science has lagged behd that human tert, ” says William Rice, an evolutnary geicist at the Universy of California, Santa Barbara, who also was not volved the work.

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

“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.

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. ’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. 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.

IS THERE A “GAY GENE"?

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. Muny there said they were worried the fdgs uld give ammunn to people who seek to e science to bolster bias and discrimatn agast gay ncern is that evince that gen fluence same-sex behavr uld e anti-gay activists to ll for gene edg or embryo selectn, even if that would be technilly impossible. “That right there is the big issue wh lookg for the geics of sexual orientatn — social ntext uld be a big part of the exprsn of the tra, ” said Jeremy Yor, an assistant profsor of blogy at California State Universy, Northridge, who is gay and follows geic rearch the field.

He and others noted that olr participants me of age when homosexual behavr was crimalized Bra and that for much of their life homosexualy was classified as a psychiatric Reilly and others said such stark differenc between olr and younger participants show the tricks of tryg to draw reprentative blogil rmatn om a study populatn so strongly fluenced by society’s changg attus.

In other words, this pattern of rults would appear to place gay men at the two extrem of the “mascule” sle, wh heterosexual mal occupyg the middle ground, “bottoms” at the lower end, and “tops” at the higher end. 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.
