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

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.

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.

THERE’S (STILL) NO GAY GENE

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. 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?

” 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. 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.

NO SGLE GENE ASSOCIATED WH BEG GAY

An early study claimed that if one pair of (male) intil tws (who have intil geic patterns) was gay, there was a 100 percent chance of the other one also beg gay. 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.

There was another, much smaller, group who said they were entirely gay (about 6 percent), and a stterg of even smaller numbers who claimed to be bisexual. 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.

“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.

IS BEG GAY GEIC?

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. ’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. 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.

'GAY GEN': SCIENCE IS ON THE RIGHT TRACK, WE'RE BORN THIS WAY. LET’S AL WH .

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. 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.

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.

"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'. "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'.

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

"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. In a recent Guardian article, Simon Copland argued that is very unlikely people are born gay (or prumably any other sexual orientatn).

Fdg evince for a blogil basis should not sre or unrme gay, lbian and bisexual (LGB) rights (the studi I refer to do not clu transgenred dividuals, so I’ll nfe my ments to lbian, gay and bisexual people). Evince om pennt rearch groups who studied tws shows that geic factors expla about 25-30% of the differenc between people sexual orientatn (heterosexual, gay, lbian, and bisexual). Tw studi are a first look to the geics of a tra and tell that there are such thgs as “gen for sexual orientatn” (I hate the phrase “gay gene”).

Three gene fdg studi showed that gay brothers share geic markers on the X chromosome; the most recent study also found shared markers on chromosome 8.

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

Perhaps this is due to the stereotype that female sexualy is “too plex” or that lbians are rarer than gay are far om the whole story. Gen uld themselv nudge one towards a particular sexual orientatn or gen may simply teract wh other environmental factors (such as sex hormon the womb environment) to fluence later sexual bras of gay and heterosexual people also appear to be anised differently. For example patterns of bra anisatn appear siar between gay men and heterosexual women and between lbian women and heterosexual men.

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

The fluence of blogy ns throughout our sexual and genred liv and those differenc, that diversy, is surely to be wrers tend to wave off the scientific evince by urgg to look to the history of sexualy or claim that homosexualy is a social nstctn (cue Michel Fouult and the like). Surely our choic are the rult of thgs we didn’t choose (our gen, personali, upbrgg, and culture) worry that scientific rearch will lead to “cur” for homosexualy (which is an odd worry to have if you don’t believe the “born this way” argument). We are who we are, and our sexuali are part of human worry about the claims of social nstctn, choice and such like is that plays to the hands of homophobic iology, to the hands of the “aversn therapists”, and to the hands of a growg culture which seeks to mimise gay differenc.

However, spe such tenuo provenance, the gay gene has persisted as a reference science news, popular science wrgs, and prs releas and edorials about bmedil rearch. News media monstrat that the gay gene has bee an assumed back-story to geic sexualy rearch over time, and that the crique of s very existence has been dimished.

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

Latterly, the gay gene has entered to the onle bmedil databas of the 21st century wh the same pattern of persistence and dimishg crique. The nsequent unmoorg of the gay gene om acuntabily and accuracy monstrat that the anizatn of bmedil databas uld benef om greater cross-disciplary attentn. Of urse, this isn’t the only environmental explanatn for how people are born gay – there are plenty of men wh olr brothers who are not gay.

This uld mean that there are some gen that are passed down om the mother’s si that make women more fertile and make men more likely to be gay. 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:.

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

"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.

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

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.

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

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.

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.

IS THERE ARE GAY GENE? ARE YOU BORN GAY OR IS BEG GAY A CHOICE?

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. 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.

IS THERE A “GAY GENE"?

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.

Grave’s disease is more mon gay than straight men, and some rearch suggts that gay men tend to be thner – which might possibly be a rult of thyroid overdrive. 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.

"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.

IS THERE A 'GAY GENE'? THE PROBLEM WH STUDI NNECTG GEICS AND LGBTQ INTY

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. 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.

Another fear is that evince that gen play only a partial role uld emboln people who sist beg gay is a choice and who advote tactics like nversn therapy. Dpe s limatns, the rearch was much larger and more varied than prev studi, which generally foced on gay men, often those who were tws or were otherwise related. “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. Dean Hamer, a former Natnal Instut of Health scientist who led the first high-profile study intifyg a geic lk to beg gay 1993, said he was happy to see such a large rearch effort.

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

“Havg said that, I’d like to emphasize that ’s not a gay gene study — ’s a study of what mak people have a sgle same-sex experience or more, ” said Dr.

Homosexuals claim that sexual orientatn is geic, and as such they nnot choose the genr to which they are attracted – they were born that way. They also claim that there are many stanc of homosexual behavr nature – that homosexual behavr has been observed over 1000 speci of animals.
