WHY ARE PEOPLE GAY? GAY BY CHOICE OR IS BEG GAY GEIC?

Scientists may have fally solved the puzzle of what mak a person gay, and how is passed om parents to their children.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 mother.The 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 lk.Long 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 not.Rice and his team created a mathematil mol that explas why homosexualy is passed through epi-marks, not geics.

HOW TO KNOW IF YOU ARE GAY

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. But bee the epi-marks provi an evolutnary advantage for the parents of homosexuals: They protect fathers of homosexuals om unrexposure to ttosterone and mothers of homosexuals om overexposure to ttosterone while they are gtatn."The epi-marks protect fathers and mothers om excs or unrexposure to ttosterone — when they rry over to oppose-sex offsprg, n e the masculizatn of femal or the femizatn of mal," Rice says, which n lead to a child beg gay.

THERE IS NO ‘GAY GENE.’ THERE IS NO ‘STRAIGHT GENE.’ SEXUALY IS JT PLEX, STUDY NFIRMS

Rice not that the markers are "highly variable" and that only strong epi-marks will rult a homosexual offsprg.Though scientists have long spected some sort of geic lk, Rice says studi attemptg to expla why people are gay have been few and far between."Most mastream blogists have shied away om studyg bee of the social stigma," he says.

Well there are many exampl of homosexualy nature, 's very mon." Homosexual behavr has been observed black swans, pengus, sheep, and other animals, he says.Rice's mol still needs to be tted on real-life parent-offsprg pairs, but he says this epigeic lk mak more sense than any other explanatn, and that his team has mapped out a way for other scientists to tt their work."We've found a story that looks really good," he says. It very much appears that same-sex sexual attractn is not a choice but actg on is; so if you fe gay as the mere prence of same-sex attractn, then om everythg we unrstand, beg gay is not a choice. If, on the other hand, you nsir someone to be gay only if they act on their same-sex attractn then beg gay n be nsired a choice pendg on an dividual's behavr.

Whether science n ultimately prove the blogy of beg gay or not, 's important to support all adults their choic no matter how they intify.

WHAT SCIENCE KNOWS ABOUT WHY PEOPLE ARE GAY

In other words, where Bud Light has buckled unr prsure as bigotry grows agast the LGBTQ+ muny, Gay Water’s creator Spencer Hodson wants his new boozy brand to be the anthis of that. “The key issue that Bud Light tapped to was the fact that they didn’t unrstand their re dience and know enough about them,” Hodson, a gay man, told CNN about the ntroversy that began when the Anhser-Bch beer brand sent fluencer Dylan Mulvaney a n of beer.

The two chatted about the limed amount of gay people wh , and wh Hodson burnt out om his tradnal day job tech, started the nned cktail. Hodson built up a strong social media followg on TikTok and Instagram durg Covid-19 and is g some of the money om that (as well as om iends and fay) to help fund Gay Water. “Gay is an umbrella term and the ia behd the brand is to be as clive as possible, which means we want alli, we want straight people to be part of this muny we’re buildg.”.

For now, Gay Water is sold largely onle (wh a few retailers) and four sugar-ee flavors — watermelon, lime, peach and grapeu — at lnch. Gay Water might not have the ep pockets pared to s petors, like Whe Claw, but “even at small sle, pani of many siz are havg succs makg spir-based seltzers and premixed cktails,” Bryan Roth, an analyst for Feel Goods Company and edor of the alhol beverage newsletter, Sightl+, told CNN.

WHY ARE THERE GAY MEN?

“There’s lots of space the spir-based seltzer tegory which Gay Water n play, pecially if the brand n offer a cultural or emotnal nnectn that will feel more excg than the prospect of another peapple-flavored vodka seltzer om natnal or ternatnal rporatns,” Roth said. Of urse, other drks e the word “gay,” too, cludg Gay Beer and So Gay Rosé, Hodson noted, which are also tryg to reach the queer muny and offer them an alternative the straight-domated space.

Specifilly, many aspects of the velopment of homosexualy (both the male and female varieti) are not as well unrstood as they should be to make some of the claims that many people felt nfint exprsg.

There's a lot to discs regardg the rults of the paper (Skorska et al, 2016): The rearchers were examg the possibily that a maternal immune rponse might play a key role the velopment of a homosexual orientatn mal.
