Michael Bronski, profsor of the practice media and activism wh the mtee on studi of women, genr, and sexualy, and thor of A Queer History of the Uned Stat, says the allure of a “gay gene” grew om the flourishg gay-rights movement the after the Stonewall rts 1969.

Exactly which gene this clter may be volved has proven elive—the current study found no signifint associatn between the X chromosome and same-sex sexual behavr—but the ia that a “gay gene” might lie somewhere Xq28—or elsewhere—was ptivatg. Zeke Stok, chief programs officer of the LGBTQ advocy anizatn GLAAD, ncurred an emailed statement: “This new study provis even more evince that beg gay or lbian is a natural part of human life, a ncln that has been drawn by rearchers and scientists time and aga.

As noted above, the gen that rrelated wh same-sex sexual behavr also rrelated wh willgns to take risks, a nnectn that might not hold up cultur where homosexualy is ls stigmatized and those who are ls risk tolerant would therefore feel more able to act openly.

It is important to note that the same-sex soc-sexual behavr observed the study is distct om homosexual behavr bee s motivatn and purpose are social, said Jean-Baptiste Le, who studi primate behavr at the Universy of Lethbridge Canada and was not volved the new rearch.

“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.
