No ‘gay gene’: Massive study hom on geic basis of human sexualy

There is no sgle “gay gene,” a new study found. Instead, sexual orientatn is like most other human tras, fluenced by a plex mix of geics and environment. * no single gay gene *

“There is no ‘gay gene’, ” says lead study thor Andrea Ganna, a geicist at the Broad Instute of MIT and Harvard Cambridge, and his lleagu also ed the analysis to timate that up to 25% of sexual behavur n be explaed by geics, wh the rt fluenced by environmental and cultural factors — a figure siar to the fdgs of smaller studi. 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.
