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. 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. “[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.

WHY ARE PEOPLE GAY? GAY BY CHOICE OR IS BEG GAY GEIC?

The largt study of s kd found new evince that gen ntribute to same-sex sexual behavr, but echo rearch that says there are no specific gen that make people gay. The genome-wi rearch on DNA om nearly half a ln U.S. and U.K. adults intified five geic variants not prevly lked wh gay or lbian sexualy. The rearchers said thoands more geic variants likely are volved and teract wh factors that aren't hered, but that none of them e the behavr nor n predict whether someone will be gay. * is gay hereditary *

While there is no sgle “gay gene, ” there is overwhelmg evince of a blogil basis for sexual orientatn that is programmed to the bra before birth based on a mix of geics and prenatal ndns, none of which the fet choos.

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. 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. Notice to Rear: "The Boards of both CERC Canada and CERC USA are aware that the topic of homosexualy is a ntroversial one that eply affects the personal liv of many North Amerins.

Both Boards strongly reerate the Catechism's teachg that people who self-intify as gays and lbians mt be treated wh 'rpect, passn, and sensivy' (CCC #2358).

Demonstratg that any behavral state, let alone one so plex, diverse s maniftatns, and nuanced as homosexualy, is not only blogil but geic is well beyond our prent rearch pacy. "To measure the relatnship between beliefs about the termants of homosexual orientatn and attus toward homosexuals, we asked 745 rponnts four societi about their beliefs ncerng the origs of homosexual orientatn. Analysis dited that subjects who believed that homosexuals are "born that way" held signifintly more posive attus toward homosexuals than subjects who believed that homosexuals choose to be that way and/or learn to be that way [2].
