THERE IS NO ‘GAY GENE.’ THERE IS NO ‘STRAIGHT GENE.’ SEXUALY IS JT PLEX, STUDY NFIRMS
There is no sgle gene rponsible for a person beg gay or a lbian. The study of nearly a half ln people clos the door on the bate around the existence of a so-lled “gay gene.
In s stead, the report fds that human DNA nnot predict who is gay or heterosexual. 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. “We worried a lot about volunteer bias, ” said Bailey, whose rearch clus a wily publicized study on Xq28 and gay brothers om 2018. Sanrs llaborated wh Bailey on those earlier studi and said their work had always admted that there was no sgle “gay gene.

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. In other words, tri to judge if a person leans gay, straight or bisexual.
“[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. Two Canadian rearchers have found a lk between the number of ridg fgerprts and male homosexualy, addg to the theory that sexual orientatn is termed before birth. The rearchers, workg at the Universy of Wtern Ontar, pared the number of ty ridg on the fgertips of 66 homosexual men wh the fgerprt patterns of 182 heterosexual men.

Thirty percent of the homosexual men showed more ridg on their left hands than their right, while only 14 percent of the heterosexual men showed the same pattern. Kimura and the study's lead thor, graduate stunt Jefey Hall, said the fgerprt patterns are not distctive to gay men or a marker for homosexualy.
Most homosexual men show the more typil pattern of more ridg on the right hand, they noted. "What we found is a statistilly signifint difference between groups of heterosexual and homosexual men, " Kimura said. Many of the gay men wh more ridg on their left hands were also left-hand.
Rearch has tablished that there is a higher cince of left-handns among gay men and lbians than the general populatn. However, Kimura and Hall found some gay men uld hear equally well out of both ears. Other rearchers have found that homosexual men tend to have a larger midsectn a bra stcture lled the anterr missure, which nnects and relays rmatn between the hemispher.
