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

Estimat as to the number of gay people the populatn range om 1--20 to 1--10, so why are some people gay? In other words, 5-10% of people experience same-sex sexual attractn or behavr; of urse, this don't speak to what mak people gay.

No one knows for certa why any dividual is gay, but the current thought is that beg gay is not a choice.

Morn science is workg to show that geics is one of the of beg gay, although some science nflicts this area. Study of fay history reveals that homosexual men have more homosexuals their fay tree than do heterosexuals. The precise gen volved the of beg gay have not yet been intified but they appear to e om the mother.

WHAT SCIENCE KNOWS ABOUT WHY PEOPLE ARE GAY

While psychologil factors may crease the likelihood that someone is gay, no sgle factor is known to e homosexualy. 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. 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.

Well, the other systematic bias that was troduced the rearch was to foc on exclively gay dividuals. I remember I gave a talk at a high school, and the parents asked, "At what age I will know for sure whether my kid is gay?

WHY ARE THERE GAY MEN?

I n't guarantee you that at age 18, if you child hasn't exprsed same-sex attractns that they won't the future—and ankly ma'am, I n't guarantee you that you are not gog to end up gay eher. While female sexualy appears to be more fluid, rearch suggts that male gayns is an born, unalterable, strongly geilly fluenced tra. But nsirg that the tra disurag the type of sex that leads to procreatn — that is, sex wh women — and would therefore seem to thwart s own chanc of beg geilly passed on to the next generatn, why are there gay men at all?

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.

Mal her only one X chromosome — the one om their mother — and if clus the gene that promot gayns mal and fecundy femal, he is likely to be gay while his mom and her female relativ are likely to have lots of kids. Prevly, the Italian rearchers suggted that the "gay man gene" might simply crease androphilia, or attractn to men, thereby makg the mal who posss the gene homosexual and the femal who posss more promiscuo.

But after vtigatg the characteristics of 161 female maternal relativ of homosexual and heterosexual men, the rearchers have adjted their hypothis. Rather than makg women more attracted to men, the "gay man gene" appears to make the women more attractive to men. 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.

HOW TO KNOW IF YOU ARE GAY

"It is que possible that there are several fluenc on formg a homosexual orientatn, " said Gelf Rieger, a sexual orientatn rearcher at Cornell Universy. But as for why geic factors would exist that make men gay, appears that the gen make women, as well as gay men, allurg to other 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.

AM I 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.

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.

” Many people, cludg sex rearchers and scientists, believe that sexual orientatn is like a sle wh entirely gay on one end and entirely straight on the other. Sexual inty is how you label yourself (for example, g labels such as queer, gay, lbian, straight, or bisexual).
