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

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. 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.

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

“[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.

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

In theory, humans and other animals who are exclively attracted to others of the same sex should be unlikely to produce many blogil children, so any gen that predispose people to homosexualy would rarely be passed on to future generatns.

Yet same-sex attractn is wispread humans, and rearch suggts that is partly a study of data om hundreds of thoands of people, rearchers have now intified geic patterns that uld be associated wh homosexual behavur, and showed how the might also help people to fd different-sex mat, and reproduce. Most of the participants were born durg a time when homosexualy was eher illegal or culturally taboo their untri, so many people who were attracted to others of the same sex might never have actually acted on their attractn, and uld therefore have end up the wrong group the Monk, an elogist and evolutnary blogist at Yale Universy New Haven, Connecticut, thks that the veats are so important that the paper n’t draw any real nclns about geics and sexual orientatn. Instead, he thks the rearchers have found geic markers associated wh openns to new experienc, which uld expla the overlap between people who have had a homosexual partner and heterosexual people who have had many partners.

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. 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.

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

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. 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.

‘I AM GAY – BUT I WASN’T BORN THIS WAY’

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. 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 BEG GAY GEIC?

You so obvly nnot be gay, was her implitn, bee this is good was 2006, a full five years before Lady Gaga would set the Born This Way argument atop s unassailable cultural perch, but even then the popular unrstandg of orientatn was that was somethg you were born wh, somethg you uldn’t change.

But what feels most accurate to say is that I’m gay – but I wasn’t born this people may fd their sir changg directn - and n't jt be explaed as experimentatn (Cred: Ignac Lehmann)In 1977, jt over 10% of Amerins thought gayns was somethg you were born wh, acrdg to Gallup.

Throughout the same perd, the number of Amerins who believe homosexualy is “due to someone’s upbrgg/environment” fell om jt unr 60% to ias reached cril mass pop culture, first wh Lady Gaga’s 2011 Born This Way and one year later wh Macklemore’s Same Love, the chos of which has a gay person sgg “I n’t change even if I tried, even if I wanted to.

IS THERE A 'GAY GENE'?

” Around the same time, the Human Rights Campaign clared unequivolly that “Beg gay is not a choice, ” and to claim that is “giv unwarranted crence to roundly disproven practic such as nversn or reparative therapy.

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

”People who challenge the Born This Way narrative are often st as homophobic, and their thkg is nsired backwardAs Jane Ward not Not Gay: Sex Between Straight Whe Men, what’s tertg about many of the claims is how transparent their speakers are wh their polil motivatns. “Such statements, ” she wr, “fe blogil acunts wh an obligatory and nearly ercive force, suggtg that anyone who scrib homosexual sire as a choice or social nstctn is playg to the hands of the enemy.

” People who challenge the Born This Way narrative are often st as homophobic, and their thkg is nsired backward – even if they are themselv, for example, Cynthia Nixon of Sex and The Cy fame.

THERE’S (STILL) NO GAY GENE

”Gay rights do not have to hge on a geic explanatn for sexualy (Cred: Ignac Lehmann)For Aravosis, and many gay activists like him, the public will only accept and affirm gay people if they thk they were born gay.

Patrick Grzanka, Assistant Profsor of Psychology at Universy of Tennsee, for stance, has shown that some people who believe that homosexualy is nate still hold negative views of gays. In fact, the homophobic and non-homophobic rponnts he studied shared siar levels of belief a Born This Way Samantha Allen not at The Daily Beast, the growg public support for gays and lbians has grown out of proportn wh the rise the number of people who believe homosexualy is fixed at birth; would be unlikely that this small change opn uld expla the spike support for gay marriage, for stance. “It don’t seem to matter as much whether or not people believe that gay people are born that way as do that they simply know someone who is currently gay, ” Allen spe of the studi, those who ph agast Born This Way narrativ have been heavily cricised by gay activists.

Siarly, Ward has received her own hatemail for phg agast the lg LGB narrativ, wh some gays tellg her she’s “worse than Ann Coulter, ” the ntroversial US thor of books like If Democrats Had Any Bras, They’d Be Republins. And when I published my say on choosg to be gay, an irate Amerin lbian activist wrote me that had “jt been nfirmed” to her that my wrg was “directly rponsible for four gay aths Rsia.

There is a unanimo opn that gay “nversn therapy” should be rejectedLet’s first be clear that whatever the origs of our sexual orientatn, there is a unanimo opn that gay “nversn therapy” should be rejected. The efforts are potentially harmful, acrdg to the APA, “bee they prent the view that the sexual orientatn of lbian, gay and bisexual youth is a mental illns of disorr, and they often ame the abily to change one’s sexual orientatn as a personal and moral failure.

The APA, for example, while notg that most people experience ltle to no choice over their orientatns, says this of homosexualy’s origs:“Although much rearch has examed the possible geic, hormonal, velopmental, social and cultural fluenc on sexual orientatn, no fdgs have emerged that perm scientists to nclu that sexual orientatn is termed by any particular factor or factors.

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

”Siarly, the Amerin Psychiatric Associatn wr a 2013 statement that while the of heterosexualy and homosexualy are currently unknown, they are likely “multifactorial cludg blogil and behavral roots which may vary between different dividuals and may even vary over time. ” Acrdg to LeVay’s rearch, a specific part of the bra, the third terstial nucls of the anterr hypothalam (INAH-3), is smaller homosexual men than is heterosexual as they might, scientists have stggled to inty any particular gen that nsistently predict the directns of our love and sire (Cred: Ignac Lehmann)Read moreYou n spot the problem wh this study a e away: were the gay bras LeVay studied born that way, or did they bee that way? Begng om his observatn that there are more gay relativ on a mother’s si than a father’s, Hamer turned his attentn to the X chromosome (which is passed on by the mother).

Bis the dividual criqu leveled agast each new study announcg some gay gene disvery, there are major methodologil cricisms to make about the entire enterprise general, as Grzanka pots out: “If we look at the raveno pursu, particularly among Amerin scientists, to fd a gay gene, what we see is that the ncln has already been arrived at. ”The other problem wh Born This Way science is summed up nicely by Simon Copland: “Scientists are askg whether homosexualy is natural when we n’t even agree exactly what homosexualy is.

” Our sir may exprs themselv many different ways that do not all nform to existg notns of ‘gay’, ‘straight’ or ‘bisexual’ is one of the bt takeaways of Ward’s Not Gay, a peratg analysis of sex between straight whe men.
