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.

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

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.

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. 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

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. 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.

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

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. The thors say their fdgs, published on 23 Augt Nature Human Behavur1, uld help to expla why gen that predispose people to homosexualy ntue to be passed down. 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. And he adms that g a sgle homosexual experience as an ditn of sexual orientatn isn’t ial, but says that the UK Bbank didn’t provi data on attractn.

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

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:.

"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.

THERE’S (STILL) NO GAY GENE

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. 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.

Notice to Rear: "The Boards of both CERC Canada and CERC USA are aware that the topic of homosexualy is a ntroversial one that eply affects the personal liv of many North Amerins.

Both Boards strongly reerate the Catechism's teachg that people who self-intify as gays and lbians mt be treated wh 'rpect, passn, and sensivy' (CCC #2358). Demonstratg that any behavral state, let alone one so plex, diverse s maniftatns, and nuanced as homosexualy, is not only blogil but geic is well beyond our prent rearch pacy. "To measure the relatnship between beliefs about the termants of homosexual orientatn and attus toward homosexuals, we asked 745 rponnts four societi about their beliefs ncerng the origs of homosexual orientatn.

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

Analysis dited that subjects who believed that homosexuals are "born that way" held signifintly more posive attus toward homosexuals than subjects who believed that homosexuals choose to be that way and/or learn to be that way [2]. Subjects one ntrol group read a summary article of rearch focg on the absence of hormonal differenc between homosexual and heterosexual men.

It reported his fdg that a lolized clter (a "nucls") of cells the bras of "homosexual" men was twice as large by volume on topsy as "heterosexual" men.

[5] ("Homosexual" and "heterosexual" are quotatns bee this study the fns of each were extremely imprecise, nor was there any way of verifyg sexual orientatn as the subjects were ad. We know om animal studi that early experience and pecially trmatic experience that pecially appli to the childhood histori of many homosexuals, alters the bra and body measurable ways.

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

Bee all human behavr is related some way to gen, we n nohels gus that one day higher qualy rearch will fd geic factors that rrelate to homosexualy. Wh rpect to whatever geic or blogil factors are rrelated to homosexualy we will need to be very reful to unrstand what they mean and ed, how limed the implitns really are.

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.

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.

IS THERE A “GAY GENE"?

’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.

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.

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. 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.
