THE LIFE OF THE GAY GENE: OM HYPOTHETIL GEIC MARKER TO SOCIAL REALY
The gay gene was first intified 1993 as a rrelatn between the geic marker Xq28 and gay male sexualy.
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. An examatn of the life of the gay gene U. 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.

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