SOME RANDOM THOUGHTS ON ‘GAY GENE’ STUDI
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 … * identical twins gay study *
Homosexual orientatn tws: a report on 61 pairs and three triplet sets. 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.
SCIENTISTS FD DNA DIFFERENC BETWEEN GAY MEN AND THEIR STRAIGHT TW BROTHERS
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. Homosexuals who are tws.
NO ‘GAY GENE’: MASSIVE STUDY HOM ON GEIC BASIS OF HUMAN SEXUALY
Is homosexualy faial?
Human homosexualy: a paradigmatic arena for sexually antagonistic selectn? Fecundy of paternal and maternal non-parental female relativ of homosexual and heterosexual men. Homosexual orientatns, pecially, may not be rrectly disclosed.
Some people are unaware that they are homosexual2. Others misreprent their homosexual orientatns bee of stigma3, 4. In some pairs of tws, both might intify as heterosexual, but one tw may not accurately disclose his/her homosexualy.
THE 'GAY GENE' IS A TOTAL MYTH, MASSIVE STUDY CONCLUS
Or, both tws uld be homosexual, but one tw may not disclose his or her same-sex preferenc. Heterosexual men rpond substantially more to femal than mal, and homosexual men rpond substantially more to mal than femal5, 6, 7, 8; th, on average, genal aroal and pupil dilatn patterns verify men’s reported sexual of all sexual orientatns rpond, on average, wh some level of aroal to erotic stimuli reprentg eher sex.
NEW TW STUDY: PEOPLE NOT BORN GAY
However, this effect is pecially mon heterosexual women, whereas homosexual women rpond somewhat more to the same sex than other sex.
The fdg that heterosexual women are non-specific their rpons to mal or femal, whereas homosexual women rpond more to their preferred sex, was nfirmed wh other measur, cludg reactn time, viewg time, nral activy, and thermography of genalia8, 14, 15, the extent that self-reported differenc intil tws’ sexual orientatns are accurate, their sexual rpons will be siar to those of most heterosexual and homosexual dividuals. Hence, male pairs, we predicted that heterosexual tws would show substantially more sexual rpons to the other sex, whereas the homosexual -tws would show more aroal to the same sex. In female pairs, we predicted that heterosexual tws would show siar sexual rpons to both sex, whereas their homosexual -tws would show somewhat stronger sexual rpons to the same sex than the other sex.
Furthermore, if tws’ sexual rpons reflect general sexual orientatn differenc, then their sexual rpons should be siar effect to the rpons seen unrelated heterosexual and homosexual dividuals.
LARGT STUDY OF GAY BROTHERS HOM ON 'GAY GEN'
RultsSexual Aroal of Male TwsWe predicted that heterosexual male tws show stronger sexual rpons to the other sex, whereas their homosexual -tws rpond more strongly to the same sex. Their homosexual -tws had signifintly more genal aroal to the same sex, p = 0. Heterosexual male tws had more genal aroal to the other sex, and their homosexual -tws showed more aroal to the same sex.
Panel A picts 5 heterosexual tws and their 5 homosexual -tws, and panel B picts 94 unrelated heterosexual men and 97 unrelated homosexual men.
GAY MEN TW STUDY
Their homosexual -tws also rpond signifintly to both sex, but somewhat more so to the same sex, p = 0. Heterosexual male tws dilated more to the other sex, and their homosexual -tws dilated more to the same sex. Panel A picts 6 heterosexual tws and their 6 homosexual -tws, and panel B picts 123 unrelated heterosexual men and 136 unrelated homosexual men.
For tws, penncy of data was acunted for by cludg pairs as a random size imageSexual Aroal of Female TwsWe predicted that heterosexual female tws show siar sexual rpons to both sex, but their homosexual -tws rpond more strongly to the same sex. Their homosexual female -tws also showed genal aroal to the same sex and other sex, each pared wh basele, although somewhat ls so for the latter, p = 0. In parison, their homosexual -tws showed somewhat more aroal to the same sex.
