SCIENTISTS FD DNA DIFFERENC BETWEEN GAY MEN AND THEIR STRAIGHT TW BROTHERS
Tw pairs which at least one tw is homosexual were soliced through announcements the gay prs and personal referrals om 1980 to the prent. An 18-page qutnnaire on the "sexualy of tws" was filled out by one or both tws. Thirty-eight pairs of monozygotic tws (34 male pairs … * twin gay men *
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. Thirty-seven of those tw sets were pairs which one was homosexual and the other was heterosexual. 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. In fact, scientists recently intified two specific gen that appear to differ between gay and straight men [1]. In s like this, some might argue that perhaps both tws are actually gay, but one jt hasn’t e out yet.
In a study where scientists looked at the sexual aroal patterns of intil tws wh different sexuali—specifilly, where one was gay and the other was straight—they found that gay tws monstrated more genal aroal rponse to same-sex imag, whereas straight tws monstrated more aroal rponse to oppose-sex imag [2]. In theory, this means two people uld rry “gay gen, ” but both of them wouldn’t necsarily be gay pendg on certa environmental factors. Tw pairs which at least one tw is homosexual were soliced through announcements the gay prs and personal referrals om 1980 to the prent.

A new study of tws provis the strongt evince yet that homosexualy has a geic basis, rearchers say, though they say other factors like social ndng may be study, published the December issue of The Archiv of General Psychiatry, adds to evince that sexual orientatn do not rult om a maladjtment or moral fect, one thor said. "We found 52 percent of intil tw brothers of gay men also were gay, pared wh 22 percent of aternal tws, pared wh 11 percent of geilly unrelated brothers, " said J.

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.
