ARE WE BORN GAY?

But on the other, he totally wrtl wh the image produced by the ia that one might be "born gay, " of a ltle male neonate appearg wh illy pk diapers and graspg a Barbie doll.

First, by ncentratg on the left si of the graphs, the rear n see that there is a segment of adult gay men who remember beg highly genr non-nformg as kids. Maybe we n agree that the image evoked by "born gay"—that ltle girl neonate appearg wearg overalls and graspg a toy tck—do not help thk through qutns of sexual sire and inty.

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.

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

“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.

” Many people, cludg sex rearchers and scientists, believe that sexual orientatn is like a sle wh entirely gay on one end and entirely straight on the other. Scientists may have fally solved the puzzle of what mak a person gay, and how is passed om parents to their children.A group of scientists suggted Tuday that homosexuals get that tra om their oppose-sex parents: A lbian will almost always get the tra om her father, while a gay man will get the tra om his mother.The heredary lk of homosexualy has long been tablished, but scientists knew was not a strictly geic lk, bee there are many pairs of intil tws who have differg sexuali. Scientists om the Natnal Instute for Mathematil and Blogil Synthis say homosexualy seems to have an epigeic, not a geic lk.Long thought to have some sort of heredary lk, a group of scientists suggted Tuday that homosexualy is lked to epi-marks — extra layers of rmatn that ntrol how certa gen are exprsed.

In homosexuals, the epi-marks aren't erased — they're passed om father-to-dghter or mother-to-son, explas William Rice, an evolutnary blogist at the Universy of California Santa Barbara and lead thor of the study."There is pellg evince that epi-marks ntribute to both the siary and dissiary of fay members, and n therefore feasibly ntribute to the observed faial herance of homosexualy and s low nrdance between [intil] tws," Rice not.Rice and his team created a mathematil mol that explas why homosexualy is passed through epi-marks, not geics. Evolutnarily speakg, if homosexualy was solely a geic tra, scientists would expect the tra to eventually disappear bee homosexuals wouldn't be expected to reproduce.

WHAT DO THE BIBLE SAY ABOUT BEG BORN GAY?

But bee the epi-marks provi an evolutnary advantage for the parents of homosexuals: They protect fathers of homosexuals om unrexposure to ttosterone and mothers of homosexuals om overexposure to ttosterone while they are gtatn."The epi-marks protect fathers and mothers om excs or unrexposure to ttosterone — when they rry over to oppose-sex offsprg, n e the masculizatn of femal or the femizatn of mal," Rice says, which n lead to a child beg gay. Rice not that the markers are "highly variable" and that only strong epi-marks will rult a homosexual offsprg.Though scientists have long spected some sort of geic lk, Rice says studi attemptg to expla why people are gay have been few and far between."Most mastream blogists have shied away om studyg bee of the social stigma," he says.

Well there are many exampl of homosexualy nature, 's very mon." Homosexual behavr has been observed black swans, pengus, sheep, and other animals, he says.Rice's mol still needs to be tted on real-life parent-offsprg pairs, but he says this epigeic lk mak more sense than any other explanatn, and that his team has mapped out a way for other scientists to tt their work."We've found a story that looks really good," he says. 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.

The news this week that the largt study of s kd failed to nfirm the existence of a "gay gene" is not so much a disappotment for those lookg to unrstand the LGBTQ muny, as is an acknowledgement that science do not need to tell what should be plaly obv: gays, lbians, bisexuals and pansexuals are who they are. But here's the quote that will light opponents of LGBTQ rights, some of whom sist they n "nvert" gay people to choose to be straight by prayg the gay away:. "There is no ‘gay gene’ that term whether someone has same-sex partners, ” said Ganna, who is also a geicist at the Broad Instute of MIT and Harvard as well as the Universy of Helski.

THE 'GAY GENE' IS A MYTH BUT BEG GAY IS 'NATURAL,' SAY SCIENTISTS

While the variatns the gen are not enough to raise a rabow flag and label anyone as unqutnably gay, the rearchers say the blogil variants may at the very least partly fluence sexual behavr.

This new rearch, he said “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.

This new rearch also renfirms the long tablished unrstandg that there is no nclive gree to which nature or nurture fluence how a gay or lbian person behav.

Geics nnot tell "the whole story, " as Eric Vila, director of the Center for Geic Medice Rearch at Children’s Natnal Health System, told the Post, about what "mak" somebody gay.

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

” The edian Bill Maher said on his show that by 2054, if we follow what he se as the current trajectory, “we will all be gay, ” addg that the rise the number of younger people intifyg as transgenr seemed spic. Bee of the fluence of Schorr put siarly Natnal Review: “To suggt that social suggtibily uld be playg a role the skyrocketg numbers of young girls’ exprsg their sire to bee mal, for example, is not of urse to say that gay and transgenr people would not exist whout the topics’ beg discsed the public square.

This is the first time Amerin history that gay and trans people have been able to live as themselv any real way, wh jobs and marriag and dogs and ts and visibily. However, blogists have documented homosexual behavr more than 450 speci, argug that same-sex behavr is not an unnatural choice, and may fact play a val role wh populatns.

IS A PERSON ‘BORN GAY’, OR IS BEG GAY A LEARNED BEHAVR?

So-lled genome-wi associatn studi intified a gene lled SLITRK6, which is active a bra regn lled the diencephalon that differs size between people who are homosexual or heterosexual. 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. Fdg evince for a blogil basis should not sre or unrme gay, lbian and bisexual (LGB) rights (the studi I refer to do not clu transgenred dividuals, so I’ll nfe my ments to lbian, gay and bisexual people).

Evince om pennt rearch groups who studied tws shows that geic factors expla about 25-30% of the differenc between people sexual orientatn (heterosexual, gay, lbian, and bisexual). Tw studi are a first look to the geics of a tra and tell that there are such thgs as “gen for sexual orientatn” (I hate the phrase “gay gene”).
