However, when the rearchers the current study examed cells om the 42 mothers who had at least two gay sons, they found that about a quarter of the women this group showed somethg different. "We thk that there are one or more gen on the X chromosome that have an effect on the sexual orientatn of the sons of the mothers, as well as an effect on the cells we were lookg at, " Bocklandt chromosom implitedBocklandt was also volved an earlier study that looked at the entire human genome of men who had two or more gay brothers. The rearchers found intil stretch of DNA on three chromosom—7, 8 and 10—that were shared by about 60 percent of the gay brothers the study also found mothers to have an unually large role their son's sexual orientatn: the regn on chromosome 10 rrelated wh homosexualy only if was hered om the rults om the two studi suggt that there are multiple geic factors volved termg a person's sexual orientatn and that might vary pendg on the person.

"We thk that there are gog to be some gay men who are X chromosome gay men and some who are chromosome 7 gay men or chromosome 10 gay men or some batn, " Bocklandt said a telephone rearchers now thk that there is no sgle gay gene that ntrols whether a person is homosexual or not. Relig lears who believe that sexual orientatn is a choice argue that such rearch is an attempt to legimize homosexualy; others worry that a tailed knowledge of the geics unrlyg homosexualy will open the door to geic engeerg that prevents Bocklandt don't thk the ncerns should prevent scientists om askg the basic qutn of whether homosexualy has an unrlyg geic ponent to or not.

In practice, if you believe the reports of men who say they are gay bee their fathers were distant, then you are bound to believe the reports of gay men who say they had close relatnships wh their fathers.

In that se, the theory fails as a general explanatn for homosexualy bee, as I illtrate below, there are numero gay men and their fathers who report histori of close bondg and mutual love. ” In that particular se, the father had actually spent more time nurturg his son durg the growg up years bee his job allowed him to work at my experience, many fathers and gay sons scribe close, lovg relatnships. For stance, one man scribed his relatnship wh his gay son this way ( alics):When my son was 18 months to 3 years old (and on to childhood), we enjoyed a wonrfully close relatnship.

A group of scientists suggted Tuday that homosexuals get that tra om their oppose-sex parents: A lbian will almost always get the tra om her father, while a gay man will get the tra om his heredary lk of homosexualy has long been tablished, but scientists knew was not a strictly geic lk, bee there are many pairs of intil tws who have differg sexuali.

Scientists om the Natnal Instute for Mathematil and Blogil Synthis say homosexualy seems to have an epigeic, not a geic thought to have some sort of heredary lk, a group of scientists suggted Tuday that homosexualy is lked to epi-marks — extra layers of rmatn that ntrol how certa gen are exprsed. In homosexuals, the epi-marks aren't erased — they're passed om father-to-dghter or mother-to-son, explas William Rice, an evolutnary blogist at the Universy of California Santa Barbara and lead thor of the study. "There is pellg evince that epi-marks ntribute to both the siary and dissiary of fay members, and n therefore feasibly ntribute to the observed faial herance of homosexualy and s low nrdance between [intil] tws, " Rice and his team created a mathematil mol that explas why homosexualy is passed through epi-marks, not geics.

Evolutnarily speakg, if homosexualy was solely a geic tra, scientists would expect the tra to eventually disappear bee homosexuals wouldn't be expected to reproduce.
