SOME RANDOM THOUGHTS ON ‘GAY GENE’ STUDI

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.

4% for homosexual orientatn.

SCIENTISTS FD DNA DIFFERENC BETWEEN GAY MEN AND THEIR STRAIGHT TW BROTHERS

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. Is homosexualy faial?

NO ‘GAY GENE’: MASSIVE STUDY HOM ON GEIC BASIS OF HUMAN SEXUALY

Human homosexualy: a paradigmatic arena for sexually antagonistic selectn?

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

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.

NEW TW STUDY: PEOPLE NOT BORN GAY

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. 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. 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.

LARGT STUDY OF GAY BROTHERS HOM ON 'GAY GEN'

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. 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.

GAY MEN TW STUDY

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.

Their homosexual -tws also rpond signifintly to both sex, but somewhat more so to the same sex, p = 0.
