SCIENTISTS FD DNA DIFFERENC BETWEEN GAY MEN AND THEIR STRAIGHT TW BROTHERS
In fact, scientists recently intified two specific gen that appear to differ between gay and straight men [1].
THE 'GAY GENE' IS A TOTAL MYTH, MASSIVE STUDY CONCLUS
For example, one may be straight while the other is gay.
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].
THE REAL STORY ON GAY GEN
In theory, this means two people uld rry “gay gen,” but both of them wouldn’t necsarily be gay pendg on certa environmental factors. Rearchers timate that jt 0.012% of the populatn nsists of a gay or bisexual person who happens to have an intil tw [2].
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.
