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

Scientists at the Karolska Instute studied bra sns of 90 gay and straight men and women, and found that the size of the two symmetril halv of the bras of gay men more closely rembled those of straight women than they did straight men. Sns of the bras of gay men the study, however, showed that their hemispher were relatively symmetril, like those of straight women, while the bras of homosexual women were asymmetril like those of straight men. It has ntued, seekg to unrstand not jt what don’t e homosexualy—playg wh dolls, growg up wh a strong mother, watchg Will and Grace—but what do.

Rell that there was a study several years back showg that women who took diet pills durg pregnancy were much more likely to have gay children. Yet, while they may tellectually agree wh the now-shopworn Sefeld tchphrase, “not that there’s anythg wrong wh that, ” most wouldn’t go so far as beg different to whether their own kid was gay.

They asked more than 477, 000 participants whether they had ever had sex wh someone of the same sex, and also qutns about sexual fantasi and the gree to which they intified as gay or straight. “A lot of people want to unrstand the blogy of homosexualy, and science has lagged behd that human tert, ” says William Rice, an evolutnary geicist at the Universy of California, Santa Barbara, who also was not volved the work.

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.

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. Specifilly, many aspects of the velopment of homosexualy (both the male and female varieti) are not as well unrstood as they should be to make some of the claims that many people felt nfint exprsg.

There's a lot to discs regardg the rults of the paper (Skorska et al, 2016): The rearchers were examg the possibily that a maternal immune rponse might play a key role the velopment of a homosexual orientatn mal.

Effectively, then, the mother's immune system would (sometim) treat certa male protes produced by the fet as a foreign pathogen and attempt to attack , rultg out that uld clu a homosexual orientatn, but also fetal loss if the reactn was strong enough (i. Already there is a lot to like about this hypothis on a theoretil level, as don't pos any hidn adaptive benefs for a homosexual orientatn (as such proposed benefs have not received sound empiril support historilly).

The rearchers reced approximately 130 mothers and classified them on the basis of what kd of children they had: those who had at least 1 gay son (n = 54), and those who only had heterosexual sons (n = 72). The mothers were then classified further to one of five groups: those wh gay male only-children (n = 8), those wh gay male offsprg that had no olr brothers (n = 23), those wh gay male offsprg wh olr brothers (n = 23), those wh heterosexual male only-children (n = 11), and those wh heterosexual male offsprg wh siblgs (n = 61). When nsired terms of the rat of misrriag to live to births, a siar picture emerged: mothers of gay male only-children reported more misrriag to live births (M = 1.
