WHAT DO THE NEW ‘GAY GEN’ TELL ABOUT SEXUAL ORIENTATN?

Dpe the associatns, the thors say that the geic siari still nnot show whether a given dividual is gay. “It’s the end of the ’gay gene, ’” says Eric Vila, a geicist at Children’s Natnal Health System Washgton, D.
“A lot of people want to unrstand the blogy of homosexualy, and science has lagged behd that human tert, ” says William Rice, an evolutnary geicist at the Universy of California, Santa Barbara, who also was not volved the work. The study will not be the last word on the vexg qutn of what homosexualy, however.
Natnal Cancer Instute and his lleagu published a paper suggtg that an area on the X chromosome lled Xq28 uld nta a “gay gene. His study, which analysed the genom of 40 pairs of gay brothers, looked exclively at people who intified as homosexual. Didn’t we already know there were “gay gen”?
MORE THAN HALF OF GENERATN Z GAY, BISEXUAL TEENAGE BOYS REPORT BEG OUT TO PARENTS
We have known for s that sexual orientatn is partly herable men, thanks to studi of fai which some people are straight and some people are gay.

Both fdgs were nfirmed a study of gay and straight brothers 2014. Alan Sanrs at North Shore Universy, Illois, and his team ppoted the gen by parg DNA om 1077 gay and 1231 straight men.

Our blogil unrstandg of homosexualy women lags behd. There have been studi suggtg that there is a geic element to homosexualy women, but more rearch has been done men, says Sanrs.
THE 'GAY GENE' IS A MYTH BUT BEG GAY IS 'NATURAL,' SAY SCIENTISTS
Why should we re about the geics of beg gay?
The latt fdgs open the prospect to intifyg the whole pathway of gen volved both homosexual and heterosexual orientatn, says Dean Hamer at the US Natnal Instut of Health, who led the study that ppoted chromosome X back 1993.
