THE 'GAY GENE' IS A TOTAL MYTH, MASSIVE STUDY CONCLUS
* 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.
STUDY: DNA OF INTIL TWS CAN REVEAL WHO'S GAY
Two sets ntaed a pair of monozygotic tws nrdant for sexual orientatn wh the third triplet dizygotic and disrdant for homosexual orientatn.
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).
GAY MEN TW STUDY
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.
