WHAT DO THE NEW ‘GAY GEN’ TELL ABOUT SEXUAL ORIENTATN?
* gay chromosome number *
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. In 1993, geic variatns a regn on the X chromosome men were lked to whether they were heterosexual or homosexual, and 1995, a regn on chromosome 8 was intified. Alan Sanrs at North Shore Universy, Illois, and his team ppoted the gen by parg DNA om 1077 gay and 1231 straight men.
Intertgly, this bra regn ntas the hypothalam, which was intified 1991 as differg size between gay and straight men.
NO ‘GAY GENE’: MASSIVE STUDY HOM ON GEIC BASIS OF HUMAN SEXUALY
LGBTQIA+ is an abbreviatn for lbian, gay, bisexual, transgenr, queer or qutng, tersex, asexual, and more. The terms are ed to scribe a person’s sexual orientatn or genr inty. * gay chromosome number *
Grave’s disease is more mon gay than straight men, and some rearch suggts that gay men tend to be thner – which might possibly be a rult of thyroid overdrive. “There will be men who have the form of gene that creas the chance of beg gay, but they won’t be gay.
SCIENTISTS FD DNA DIFFERENC BETWEEN GAY MEN AND THEIR STRAIGHT TW BROTHERS
There have been studi suggtg that there is a geic element to homosexualy women, but more rearch has been done men, says Sanrs.

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. However, blogists have documented homosexual behavr more than 450 speci, argug that same-sex behavr is not an unnatural choice, and may fact play a val role wh populatns. The 2019 study is the latt a hunt for “gay gen” that began 1993, when Dean Hamer lked male homosexualy to a sectn of the X chromosome.
As the ease and affordabily of genome sequencg creased, addnal gene ndidat have emerged wh potential lks to homosexual behavr. So-lled genome-wi associatn studi intified a gene lled SLITRK6, which is active a bra regn lled the diencephalon that differs size between people who are homosexual or heterosexual.
THERE’S (STILL) NO GAY GENE
Wh multiple gene ndidat beg lked to homosexualy, seemed highly unlikely that a sgle “gay” gene exists. Several hypoth have been advanced to expla how homosexualy n be beneficial perpetuatg faial gen.

Gay uncl and nts, for example, are “helpers the nt” that help raise other fay members’ children to nurture the fay tree. ” For example, certa gen women help crease their fertily, but if the gen are exprsed a male, they predispose him toward homosexualy.
While there is no sgle “gay gene, ” there is overwhelmg evince of a blogil basis for sexual orientatn that is programmed to the bra before birth based on a mix of geics and prenatal ndns, none of which the fet choos. It wouldn't be right if we didn't mentn this new rearch supportg the hypothis that sexual orientatn has got a geic rearch adds a twist to the bate on the origs of sexual orientatn, suggtg that the geics of mothers of multiple gay sons act differently than those of other women. Scientists found that almost one fourth of the mothers who had more than one gay son procsed X chromosom their bodi the same way.
