THERE’S NO ONE ‘GAY GENE,’ BUT GEICS ARE LKED TO SAME-SEX BEHAVR, NEW STUDY SAYS
2% of women and men, rpectively, intify as gay. Dpe the numbers, many people still nsir homosexual behavr to be an anomalo choice.
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 hunt for ‘gay gen’.
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.
THERE IS NO ‘GAY GENE.’ THERE IS NO ‘STRAIGHT GENE.’ SEXUALY IS JT PLEX, STUDY NFIRMS
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.
Wh multiple gene ndidat beg lked to homosexualy, seemed highly unlikely that a sgle “gay” gene exists. In rats, manipulatn of hormon durg pregnancy produc offsprg that exhib homosexual behavr.
Why do homosexual behavr exist? Several hypoth have been advanced to expla how homosexualy n be beneficial perpetuatg faial gen. Gay uncl and nts, for example, are “helpers the nt” that help raise other fay members’ children to nurture the fay tree.

Another ia suggts that homosexualy is a “tra-off tra. ” 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. 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. 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.

Current rearch timat that 8% of the populatn is gay, and has been known that homosexualy n n fai. If one of a set of intil tws is gay, there’s a 20% chance that the other will be, too. Homosexualy isn’t jt tied to the human speci.
There are many speci exhibg homosexual tras, cludg fish and birds, and geicists have not been able to fd a gene that is rponsible for sexual orientatn. The thors propose that homosexualy may be a rry-over om one’s parents’ own prenatal gen to rist excs ttosterone, and this uld alter the gene activatn areas of the child’s bra volved sexual attractn and preference. This uld expla why homosexualy persists throughout evolutn, state the om chang gene exprsn to why someone is attracted to a person of the same sex is probably a qutn for which science may never fd the answer, stat Marlene Z, an evolutnary blogist at the Universy of Mnota, Tw Ci.
