The largt study of s kd found new evince that gen ntribute to same-sex sexual behavr, but echo rearch that says there are no specific gen that make people gay. The genome-wi rearch on DNA om nearly half a ln U.S. and U.K. adults intified five geic variants not prevly lked wh gay or lbian sexualy. The rearchers said thoands more geic variants likely are volved and teract wh factors that aren't hered, but that none of them e the behavr nor n predict whether someone will be gay.

“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.
WHAT DO THE NEW ‘GAY GEN’ TELL ABOUT SEXUAL ORIENTATN?
“[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.
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.
IS THERE A "GAY GENE"? MAJOR NEW STUDY SAYS NO
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. 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.

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.
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.

THE 'GAY GENE' IS A TOTAL MYTH, MASSIVE STUDY CONCLUS
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. 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.
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. "Former Natnal Instut of Health geicist Dean Hamer said the study nfirms "that sexualy is plex and there are a lot of gen volved, " but isn't really about gay people.

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.
