THERE IS NO ‘GAY GENE.’ THERE IS NO ‘STRAIGHT GENE.’ SEXUALY IS JT PLEX, STUDY NFIRMS
A new study argu that there's no sgle "gay gene," but rather several geic variants that partially expla same-sex sexual activy. * a homosexual gene *
The study of nearly a half ln people clos the door on the bate around the existence of a so-lled “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.
THERE'S NO SUCH THG AS A 'GAY GENE,' A NEW STUDY ARGU
The gay gene was first intified 1993 as a rrelatn between the geic marker Xq28 and gay male sexualy. The rults of this origal study were never replited, and the blogil realy of such an enty remas hypothetil. However, spe such tenuo provenance, the gay gene has p … * a homosexual gene *
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.
SEARCH FOR 'GAY GEN' COM UP SHORT IN LARGE NEW STUDY
The claim that homosexual men share a “gay gene” created a furore the 1990s. But new rearch two s on supports this claim – and adds another ndidate gene. To an evolutnary geicist, the… * a homosexual gene *
“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 (STILL) NO GAY GENE
Two gene variants have been found to be more mon gay men. New Scientist looks at what this tells about the way blogy shap our sexualy * a homosexual 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.
NO ‘GAY GENE’: MASSIVE STUDY HOM ON GEIC BASIS OF HUMAN SEXUALY
* a homosexual gene *
“[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.
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. The law also might take a different view those untri (aga, there are still many) which beg gay is a crimal offense. 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.
THE LIFE OF THE GAY GENE: OM HYPOTHETIL GEIC MARKER TO SOCIAL REALY
There is no sgle “gay gene,” a new study found. Instead, sexual orientatn is like most other human tras, fluenced by a plex mix of geics and environment. * a homosexual gene *
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. Firstly, they found very few gen whose variatns were rrelated wh beg gay, or even havg a sgle same-sex partner. In 1993, rearchers disvered a stretch of DNA on the X chromosome they believed to be lked to male homosexualy.
In the years sce, the ncept of a “gay gene” has been a source of bate wh both the scientific muny and the general public, spirg ever-larger follow-up studi over the years. After studyg the DNA of nearly half a ln people wh varyg sexual experienc, the rearchers found no evince of a sgle “gay gene.
IS THERE A “GAY GENE"?
In fact, Ganna says the rearch suggts that measur like the Ksey Sle, which argue that sexualy exists on a spectm om totally gay to totally straight, are overly simplistic. ” The study leav many qutns unanswered, part bee alt wh a fairly homogeno sample: people of European anctry, many of whom me of age durg a time when homosexualy was highly stigmatized or even crimalized. “This is a natural and normal part of variatn our speci, and that should support the posn that we shouldn’t try and velop ‘gay cur.
THE 'GAY GENE' IS A TOTAL MYTH, MASSIVE STUDY CONCLUS
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. 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’S NO EVINCE THAT A SGLE ‘GAY GENE’ EXISTS
“There is no sgle gay gene, but rather the ntributn of many small geic effects sttered across the genome, ” he emphasized.
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. 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.
THERE’S NO ONE ‘GAY GENE,’ BUT GEICS ARE LKED TO SAME-SEX BEHAVR, NEW STUDY SAYS
’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.
WHAT DO THE NEW ‘GAY GEN’ TELL ABOUT SEXUAL ORIENTATN?
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. “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. 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. 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. 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.
NO SGLE ‘GAY GENE’ TERM SAME-SEX SEXUAL BEHAVR, DNA ANALYSIS FDS
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. Latterly, the gay gene has entered to the onle bmedil databas of the 21st century wh the same pattern of persistence and dimishg crique. Prs and onle databas to reprent the procs through which the addrs of the gay gene has shifted and bee an x of bmedilizatn.
IS THERE A 'GAY GENE'? THE PROBLEM WH STUDI NNECTG GEICS AND LGBTQ INTY
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. But even more pellg is their argument that the different ways of beg gay also lead to different ways of beg gay.
Gay men often tegorize themselv to what they ll “tops” and “bottoms” ('s also possible to be a "swch"). 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.
In sum, the data suggt that askg whether there’s a “gay gene” isn’t the right way to thk about the issue. 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.
