Talk to the hand. (Research).Lesbian researcher Lynn S. Hall says her studies of identical twins identical twins pl.n. Twins derived from the same fertilized ovum that at an early stage of development becomes separated into independently growing cell aggregations, giving rise to two individuals of the same sex, identical genetic makeup, and indicate that factors in the prenatal environment--probably hormonal--influence sexual orientation sexual orientation n. The direction of one's sexual interest toward members of the same, opposite, or both sexes, especially a direction seen to be dictated by physiologic rather than sociologic forces. . In 1996 and 1997, Hall traveled across America taking fingerprints of twins--a control set of gay twins and a group of twins in which the siblings are genetically identical but at opposite ends of the Kinsey scale. Initially Hall found that in sets of gay twins, both brothers or sisters had the same number of ridges on their fingers. Not so in the pairs of gay-straight twins. Hall, who works at New York University New York University, mainly in New York City; coeducational; chartered 1831, opened 1832 as the Univ. of the City of New York, renamed 1896. It comprises 13 schools and colleges, maintaining 4 main centers (including the Medical Center) in the city, as well as the Medical School, next looked at finger length. And in a study published in the February issue of the Archives of Sexual Behavior Archives of Sexual Behavior is an academic sexology journal and the official publication of the International Academy of Sex Research. Contributions consist of empirical research (both quantitative and qualitative), theoretical reviews and essays, clinical case , she reported that gay twins differed from their straight siblings in the lengths of their digits. Still, Hall said, "this doesn't mean you can look at somebody's hand and tell whether they are gay." |
