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

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.

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

“[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. Perhaps sexual preference n be changed – and people have the right to engage gay sex and have homosexual relatnships if they choose to do so.

In 1993, a study published the journal Science showed that fai wh two homosexual brothers were very likely to have certa geic markers on a regn of the X chromosome known as Xq28. In some societi, homosexualy is accepted, others, is owned upon but tolerated, yet others, is a ser crimal offense, possibly punishable by ath.

Some people might argue that if you are “geilly gay” but the thought of homosexualy nseat you, then you jt haven’t accepted the fact that you really are gay. That argument is based on the assumptn that sexual preference is purely blogil; therefore, has no place a discsn about the possible of homosexualy.

SCIENTISTS MAY HAVE FALLY UNLOCKED PUZZLE OF WHY PEOPLE ARE GAY

In 1991, a study published the journal Science seemed to show that the hypothalam, which ntrols the release of sex hormon om the puary gland, gay men differs om the hypothalam straight men. This study was cricized bee ed bra tissue obtaed at topsi, and all of the homosexual subjects the study were believed to have died of AIDS. This study, which also ed bra tissue om topsi, did not reveal any signifint difference between the size of the INAH3 gay men and straight men.

PET and MRI studi performed 2008 have shown that the two halv of the bra are more symmetril homosexual men and heterosexual women than heterosexual men and homosexual women.

The studi have also revealed that nnectns the amygdalas of gay men remble those of straight women; gay women, nnectns the amygdala remble those of straight men. Some studi have shown that the rp llosum – the ma nnectn between the two halv of the bra- has a different stcture gay men than straight men.

Gay women and gay men are more likely to be left-hand or ambixtro than straight women and straight men, acrdg to a number of different studi. Today, however, we know much more about the bra than we did when homosexualy was nsired a disease that required treatment, and the amount of knowledge that we have about the bra is creasg. If we fe beg gay as engagg homosexual behavr (the ncept of “gay” as an inty is a Wtern cultural ncept – people who have sex wh both men and women may ll themselv gay, straight or bisexual, pendg on the l of their culture or subculture), then people stop beg gay as soon as they stop engagg this behavr.

I believe that people have the right to engage any behavr that they choose, as long as their actns do not harm others, and I believe that gay sex and gay relatnships do not e harm to anyone. (Of urse, there are abive and unhealthy gay relatnships that should not be tolerated, jt as there are unhealthy heterosexual relatnships that should not be tolerated. If sexual preference n be altered, then people who support gay rights n’t rely on the argument that gay people should be protected om discrimatn bee gay people have no choice but to be gay – an argument that seems like an apology for homosexualy, as if homosexualy is a disease for which there is no cure.

WHY ARE THERE GAY MEN?

Jt as gay people who are happy as they are should not be forced to change their sexual orientatn, gay people who want to be straight should have the right to change if they n – and the rrect word is “change” – not “cure”.

It very much appears that same-sex sexual attractn is not a choice but actg on is; so if you fe gay as the mere prence of same-sex attractn, then om everythg we unrstand, beg gay is not a choice. If, on the other hand, you nsir someone to be gay only if they act on their same-sex attractn then beg gay n be nsired a choice pendg on an dividual's behavr. 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 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 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.

HOW TO KNOW IF YOU ARE GAY

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 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.

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 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.

GAY STEREOTYP: ARE THEY TE?

" Homosexual behavr has been observed black swans, pengus, sheep, and other animals, he '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. “Let me tell you a story, ” he said, rellg the time he reprented a heterosexual woman a se agast gay neighbors who were tryg to have her dog put down. ’ There’s this ia, pecially among gay men, that guys who say they’re bisexual are lyg, on their way to beg gay, or jt kd of unser and unfoced.
