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

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 … * gay twins statistics *

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]. Tw pairs which at least one tw is homosexual were soliced through announcements the gay prs and personal referrals om 1980 to the prent. Two sets ntaed a pair of monozygotic tws nrdant for sexual orientatn wh the third triplet dizygotic and disrdant for homosexual orientatn.

STUDY: DNA OF INTIL TWS CAN REVEAL WHO'S GAY

Most of the more recent rearch on possible blogil origs of homosexualy has foced on the gree to which gen, along wh other prenatal factors such as hormon and epi-geics, may fluence the velopment of homosexualy. The former approach of recg intil tws via advertisements gay and lbian publitns is now known to have a very strong “volunteer effect” that produced the appearance of relatively large geic effects (1). Neverthels, even wh the e of large tw registri, the number of intil tw pairs found wh homosexualy is often very small dividual studi, rultg a standard viatn that is greater than the lculated geic effect, meang that the rults are not statistilly different om zero.

Whehead and Whehead (1) have prented and discsed, some tail, the and other problems herent tw studi of homosexualy and have prented reasons to expect that the geic fluence on, or ntributn to, homosexualy will eventually be agreed to be the 10%-15% range (i.

Another reason has to do wh the apparently predomant fluence of post-natal environmental factors on the velopment of homosexualy (10). Schumm (9) found that children wh homosexual parents are 12-15 tim more likely than children of heterosexual parents to be homosexual as adults. This is the strongt environmental fluence ever reported for the velopment of homosexualy, and volv very close fay members, the parent-child relatnship.

The rults of a study by Kg and McDonald (8) illtrate how such a close, fay relatnship uld flate the lculated geic fluence on homosexualy  intil tw studi. They studied 46 tw pairs havg homosexualy prent one or both of the tws each pair and found that 54% of the tw pairs had discsed their sexual orientatn wh each other, 89% had “shared knowledge” of each other’s sexual orientatn, and 30% of the tw pairs had actually had sex wh each other. Bee intil tws intify so closely wh each other, and post-natal experienc – pecially close fay relatnships – strongly affect the velopment of homosexualy, seems plsible, if not likely, that a homosexual member of a tw pair would fluence the other member of that pair to embrace and explore homosexualy also, th flatg the apparent geic fluence reported intil tw studi.

That is to say, a signifint portn of what may appear, intil tw studi, to be a geic fluence on the velopment of homosexualy may turn out to be, stead, a post-natal, environmental fluence volvg shared knowledge of sexual orientatn and shared sexual experienc wh intil tw pairs. The “pair-wise nrdance” answers the simple qutn, “Where one tw of an intil pair is homosexual, what percentage of -tws is also homosexual”. The pair-wise nrdance valu dite that for every tw pair wh both members beg homosexual, there are 7 tw pairs wh only one homosexual member.
