WHY ARE THERE GAY MEN?
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. 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.
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.
WHAT SCIENCE KNOWS ABOUT WHY PEOPLE ARE GAY
Part of the explanatn is geic, but bee most intil tws of gay people are straight, heredy don’t expla “why” qutn is important bee “there is a strong rrelatn between beliefs about the origs of sexual orientatn and tolerance of non-heterosexualy, ” acrdg to the report thors, who are om seven universi spanng the globe.
WHY ARE THERE GAY WOMEN?
But gaps will rema, such as why some firstborn sons are gay, why some intil tws of gay sons are straight, and why women are gay, to name jt a review-paper thors do le out one explanatn for homosexualy, however: That tolerance for gay people enurag more people to bee gay. “Homosexual orientatn do not crease equency wh social tolerance, although s exprsn ( behavr and open intifitn) may do so, ” they reasong—that a tolerant society somehow enurag homosexualy to flourish—has been ed to support anti-gay legislatn Uganda, Rsia, and elsewhere.
For several years, studi led by Andrea Camper Ciani at the Universy of Padova Italy and others have found that mothers and maternal nts of gay men tend to have signifintly more offsprg than the maternal relativ of straight men. The rults show strong support for the "balancg selectn hypothis, " which is fast beg the accepted theory of the geic basis of male theory holds that the same geic factors that duce gayns mal also promote fecundy (high reproductive succs) those mal' female maternal relativ.
Through this tra-off, the maternal relativ' "gay man gen, " though they aren't exprsed as such, tend to get passed to future generatns spe of their tenncy to make their male herors no one knows which gen, exactly, the might be, at least one of them appears to be loted on the X chromosome, acrdg to geic molg by Camper Ciani and his lleagu. The androphilic pattern that we found is about femal who crease their reproductive value to attract the bt mal, " Camper Ciani told Life's Ltle out, the moms and nts of gay men have an advantage over the moms and nts of straight men for several reasons: They are more fertile, displayg fewer gynelogil disorrs or plitns durg pregnancy; they are more extroverted, as well as funnier, happier and more relaxed; and they have fewer fay problems and social anxieti.

WHY WOULD PEOPLE 'CHOOSE' TO BE GAY?
Recently, scientists announced that they found some gen that might be associated wh sexual orientatn and a blogil explanatn for the reason gay men tend to have olr the field of sexual orientatn rearch is far broar and more plited than two studi—and Lisa Diamond, a psychologist and sexual orientatn rearcher at the Universy of Utah, knows that better than most. Homosexual members of society n unfortunately expect to regularly be challenged, sctised and nmned by belligerent type who are seemgly nvced that homosexualy is a “liftyle choice” issue has e up aga (for what is possibly the 12, 456, 987, 332nd time) for several reasons. The mastream media has always been somewhat blunt or ham-fisted s portrayal of even heterosexual relatnships (for evince of this, see pretty much any married uple an advert), so was a long shot that they’d show homosexuals accurately.

Normally heterosexual characters sudnly displayg homosexual leangs when a boost viewg figur are need is a mon trope the days, so you n sort of see how this might make some people thk ’s a “choice”, if they lack more realistic sayg that sexualy is set stone om birth is also not que right, the ma emphasis of those g the choice argument is that homosexuals have weighed up their optns and nscly cid “I am gog to be gay om now on”. Comedian Todd Glass mak a brilliant pot his book (which is great, I got for Christmas), which is that if you genuely believe sexualy is a choice, then you’re not actually straight, you jt haven’t met anyone persuasive enough those who argue that homosexualy is a choice variably assert that is a wrong choice. The term “homosexualy, ” while sometim nsired anachronistic the current era, is the most applible and easily translatable term to e when askg this qutn across societi and languag and has been ed other cross-natnal studi, cludg the World Valu Survey.
