LARGT STUDY OF GAY BROTHERS HOM ON 'GAY GEN'
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 … * twins gay study *
In fact, scientists recently intified two specific gen that appear to differ between gay and straight men [1]. 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]. 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.

8% for homosexual orientatn. 4% for homosexual orientatn.
Two sets ntaed a pair of monozygotic tws nrdant for sexual orientatn wh the third triplet dizygotic and disrdant for homosexual orientatn. A third triplet set was monozygotic wh all three nrdant for homosexual orientatn. N help expla why someone is gay or straight, relig or not, bray or not, and even whether they're likely to velop gum disease, one psychologist broad-rangg geic effects first me to light a landmark study — Mnota Tw Fay Study — nducted om 1979 to 1999, which followed intil and aternal tws who were separated at an early age.

Not a liftyle thg, but specific gay gen rema to be pned down(Image: amc / Alamy). 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. The only tra unequivolly shared by all 818 men was beg gay.
But this don’t mean the study found two “gay gen”. 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. Lear: “Gay gene disvery has good and bad implitns“. 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.
