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. Do matter if there is a geic tenncy for beg gay?
THERE’S NO EVINCE THAT A SGLE ‘GAY GENE’ EXISTS
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.

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. A dramatic claim was that there was a sgle geic variatn, the "gay gene, " that was found gay men.
THE LIFE OF THE GAY GENE: OM HYPOTHETIL GEIC MARKER TO SOCIAL REALY
Alas, like so many other early reports of a "gay gene, " this one uld not be repeated.
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. Firstly, they found very few gen whose variatns were rrelated wh beg gay, or even havg a sgle same-sex partner.
Overall, geic variatns acunted for only around 1 percent of the likelihood of beg gay. But as stands, there’s no sign of a "gay gene.
