SCIENTISTS FD DNA DIFFERENC BETWEEN GAY MEN AND THEIR STRAIGHT TW BROTHERS

Ngun reported that studyg the geic material of 47 pairs of intil male tws, he has intified “epigeic marks” ne areas of the human genome that are strongly lked to male dividuals, said Ngun, the prence of the distct molecular marks n predict homosexualy wh an accuracy of close to 70%. Geicists suggt that together, the human genome and s epigenome reflect the teractn of nature and nurture -- both our fixed herance and our bodi’ flexible rpons to the world -- makg who we ’s study of tws don’t reveal how or when a male tak on the epigenomic marks that distguish him as homosexual.

”To fd the epigenomic markers of male homosexualy, Ngun, a postdoctoral rearcher at UCLA’s Geffen School of Medice, bed through the geic material of 47 sets of intil male tws. But the existence of tw pairs which one is homosexual and the other is not offers strong evince that somethg other than DNA alone fluenc sexual orientatn. So they unleashed a mache learng algorhm on the data to search for regulari that distguished the epigenom of homosexual tw-pairs om tws which only one was ne pact regns sttered across the genome, they found patterns of epigenomic differenc that would allow a predictn far more accurate than a random gus of an dividual’s sexual orientatn, Ngun reported Thursday.

McCarthy and other experts utned that the disvery of epigenomic marks suggtive of homosexualy is a far cry om fdg the of sexual distctive epigenomic marks observed by Ngun and his lleagu uld rult om some other blogil or liftyle factor mon to homosexual men but unrelated to their sexualy, said Universy of Utah geicist Christopher Gregg. But the existence of intil tw pairs which only one is homosexual “nclively suggt that gen don’t expla everythg, ” Bailey Ngun’s rearch needs to be replited larger studi of tws, advanc the fful procs of better unrstandg how — and when — a boy’s sexual orientatn velops, Bailey me on Twter @LATMelissaHealy and “like” Los Angel Tim Science & Health on rarely get ncer, now scientists thk they know whyThree rearchers w Nobel Prize chemistry for studi of DNA repairMars had a long-lastg seri of lak, NASA’s Cursy rover fds. Tw studi of homosexualy have shown that intil tws are about twice as likely to both be gay pared to aternal tws.

If the DNA sequence were the only thg termg whether someone is gay or not, we would expect intil tws to match 100% of the time. Of urse, this isn’t the only environmental explanatn for how people are born gay – there are plenty of men wh olr brothers who are not gay. This uld mean that there are some gen that are passed down om the mother’s si that make women more fertile and make men more likely to be gay.

No matter why those gen are still around, we do know that beg gay is partly geic and partly termed before a baby is even born. Scholars at Johns Hopks Universy released a new report on Monday which argu that there is not sufficient evince to suggt that lbian, gay, or transgenr people are born wh this sexual orientatn or genr inty. “There are probably some people that intify as hetrosexual [sic] that then later on intified as homosexual, so go both ways.

JOHNS HOPKS REARCH: NO EVINCE PEOPLE ARE BORN GAY OR TRANSGENR

The three-part, 143-page report, which appeared the Fall 2016 edn of The New Atlantis, also vtigated other monly accepted ias about homosexualy and transgenrism.

Mayer and his -thor Pl McHugh, a profsor of psychiatry and behavral scienc at Johns Hopks, challenged the claim that discrimatn and social stigma are the only reasons why homosexual and transgenr people suffer higher rat of mental health problems and are more likely to m suici.

The study breaks down three parts: First, Mayer and McHugh examed whether homosexualy is an hered tra, and nclud that people are not simply “born that way.

THE 'GAY GENE' IS A TOTAL MYTH, MASSIVE STUDY CONCLUS

” Send, they looked at the of the poor mental health associated wh gay and transgenr people, ncludg that social strs do not expla all of . “Studi of the bras of homosexuals and heterosexuals have found some differenc, but have not monstrated that the differenc are born rather than the rult of environmental factors that fluenced both psychologil and nroblogil tras, ” the report explaed. For women, both tws had at least one homosexual partner 22 percent of intil tws and 17 percent of aternal tws.

There is virtually no evince that anyone, gay or straight, is ‘born that way’ if means that their sexual orientatn was geilly termed, ” the report explaed (emphasis add).

NEW TW STUDY: PEOPLE NOT BORN GAY

“But there is some evince om the tw studi that certa geic profil probably crease the likelihood the person later intifi as gay or engag same-sex sexual behavr. The report also found that gay and transgenr people are at elevated risk for a variety of mental health risks, cludg anxiety disorrs, prsn, substance abe, and suici. If their DNA gen are “intil, ” now that they are adults, how n one be homosexual, while his tw is married wh children?

Studi have shown that intil tws, if one tw is gay (the term “homosexual” is ed clil studi but is nsired offensive, so I won’t e further), then 30 per cent to 66 per cent of the intil tws also will be gay. However, an adopted siblg of a gay person is also more likely to be gay (11 per cent one study), suggtg that the faial environment also plays a signifint role. No dividual gene alone mak a person gay, lbian or bisexual; stead, thoands of gen likely fluence sexual orientatn, a massive new study of the genom of nearly half a ln people human societi and both sex, between 2% and 10% of people report engagg sex wh a member of the same sex, eher exclively or addn to sex wh a member of the oppose sex, the rearchers said.

Consir the followg and ask yourself this qutn: Why are scientists workg to overe the geic irregulari but not homosexualy which is geilly unter productive?

After years of tryg to prove a geic basis to homosexualy, the evince is mountg that homosexualy is not ed by a person's gen. " [Holland] It appears that the preceptn of life-events has a greater impact on whether a person se himself as a homosexual. In the study by Bailey, "His team asked non-nrdant intil tws (one was homosexual, one not) about their early fay environment, and found that the same fay environment was experienced or perceived by the tws que different ways.

About half of the homosexual / bisexual populatn ( a non-theraptic environment) mov towards heterosexualy over a lifetime. 16 year olds sayg they are SSA or Bi-attracted are 25 tim more likely to say they are the oppose sex attracted at the age of 17 than those wh a heterosexual orientatn are likely to intify themselv as bi-sexual or homosexual.

A geic analysis of 409 pairs of gay brothers, cludg sets of tws, has provid the strongt evince yet that gay people are born gay. The fdg is an important ntributn to mountg evince that beg gay is blogilly termed rather than a liftyle choice. In some untri, such as Uganda, beg gay is still crimalised, and some relig groups believe that gay people n be “treated” to make them straight.

Over the past five years, Sanrs has llected blood and saliva sampl om 409 pairs of gay brothers, cludg non-intil tws, om 384 fai. Sanrs says he has already pleted the work for that next step: he has pared SNPs those specific regns gay and straight men to see if there are obv differenc the gene variants, and is now preparg the rults for publitn. “This study knocks another nail to the ff of the ‘chosen liftyle’ theory of homosexualy, ” says Simon LeVay, the nroscientist and wrer who, 1991, claimed to have found that a specific bra regn, wh the hypothalam, is smaller gay men.

“Y, we have a choice life, to be ourselv or to nform to someone else’s ia of normaly, but beg straight, bisexual or gay, or none of the, is a central part of who we are, thanks part to the DNA we were born wh. As a gay man, I’ve known that my sexualy has never been a choice but I uld not expla, to myself or anyone else, how I beme this way. They might possibly change the mds of those who believe homosexualy is a “choice” rather than somethg pretermed.

The gen, if and when they are intified, may only predispose one to the possibily of beg gay, should the required environmental, nutrnal or other unknown factors be prent at cril stag of velopment.
