THERE IS NO ‘GAY GENE.’ THERE IS NO ‘STRAIGHT GENE.’ SEXUALY IS JT PLEX, STUDY NFIRMS

Y, a growg body of knowledge is ditg that homosexualy n n fai, although this often has been hidn many s and not discsed openly. Acrdg to thors Barbara and Allan Pease, there is a greater chance of a male beg gay if he has brothers, uncl, s, or parents (more on the mother’s si) who are also gay.

A iend of me recently disvered—to his great surprise—that his mother was lbian and that two maternal s are gay (one male and one female) along wh a paternal uncle. Psychologist Anthony Bogaert of Brock Universy Ontar Canada reported that the risk of beg gay creas wh the number of olr brothers.

A 1995 news release om Stanford Universy dited that the probabily that the brother of a gay man is gay is about four tim higher than normal. However, male homosexualy and lbianism tend to n different fai: sisters wh gay brothers are not more likely than normal to be lbian.

NEW STUDY FDS GEICS INFLUENCE LGBTQ SEXUALY, BUT STILL NO 'GAY GENE'

A 1993 study that traced the pedigree of pairs of gay brothers found that homosexualy tends to n on the maternal si of the fay tree: the brothers had a higher than average number of maternal nephews and uncl who are gay. Scientists, led by Dean Hamer, an Aids rearcher at the US Natnal Cancer Instute, studied the fay histori of 114 gay mal and found that 13.

The study of nearly a half ln people clos the door on the bate around the existence of a so-lled “gay gene. 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.
