WHAT DO THE NEW ‘GAY GEN’ TELL ABOUT SEXUAL ORIENTATN?
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 * gay gen *
A clear geic lk would suggt that gay people are “born this way, ” as opposed to havg ma a liftyle choice. Yet some fear that such a fdg uld be mised “cure” homosexualy, and most rearch teams have shied away om tacklg the topic. 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.
Dpe the associatns, the thors say that the geic siari still nnot show whether a given dividual is gay. “It’s the end of the ’gay gene, ’” says Eric Vila, a geicist at Children’s Natnal Health System Washgton, D.
“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. The study will not be the last word on the vexg qutn of what homosexualy, however. Natnal Cancer Instute and his lleagu published a paper suggtg that an area on the X chromosome lled Xq28 uld nta a “gay gene.
THERE’S NO ONE ‘GAY GENE,’ BUT GEICS ARE LKED TO SAME-SEX BEHAVR, NEW STUDY SAYS
His study, which analysed the genom of 40 pairs of gay brothers, looked exclively at people who intified as homosexual. Didn’t we already know there were “gay gen”?
MORE THAN HALF OF GENERATN Z GAY, BISEXUAL TEENAGE BOYS REPORT BEG OUT TO PARENTS
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. Both fdgs were nfirmed a study of gay and straight brothers 2014.
THERE IS NO ‘GAY GENE.’ THERE IS NO ‘STRAIGHT GENE.’ SEXUALY IS JT PLEX, STUDY NFIRMS
Alan Sanrs at North Shore Universy, Illois, and his team ppoted the gen by parg DNA om 1077 gay and 1231 straight men. Intertgly, this bra regn ntas the hypothalam, which was intified 1991 as differg size between gay and straight men.
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.
Are all men who have the “gay” variants of the gen gay?
SEARCH FOR 'GAY GEN' COM UP SHORT IN LARGE NEW STUDY
“There will be men who have the form of gene that creas the chance of beg gay, but they won’t be gay. What about women who are gay?
Our blogil unrstandg of homosexualy women lags behd. There have been studi suggtg that there is a geic element to homosexualy women, but more rearch has been done men, says Sanrs.
NO ‘GAY GENE’: MASSIVE STUDY HOM ON GEIC BASIS OF HUMAN SEXUALY
Why should we re about the geics of beg gay?
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. Read more: Evolutn myths: Natural selectn nnot expla homosexualy.
To evolutnary blogists, the geics of homosexualy seems like a paradox. 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.
THE 'GAY GENE' IS A MYTH BUT BEG GAY IS 'NATURAL,' SAY SCIENTISTS
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. No ‘gay gene’: Massive study hom on geic basis of human sexualy.
IS THERE A "GAY GENE"? MAJOR NEW STUDY SAYS NO
None of the variatns seemed to greatly affect sexual behavur on s own, backg up prev rearch that has found no sign of a ‘gay gene’. 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 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. For stance, rearch has shown patterns fai wh multiple men the same fay intifyg as gay.
