SCIENTISTS MAY HAVE FALLY UNLOCKED PUZZLE OF WHY PEOPLE ARE GAY
Theory: Lbians get om their fathers, gay men om their mothers. * why is a person gay *
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 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 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 and his team created a mathematil mol that explas why homosexualy is passed through epi-marks, not geics.
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 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. Well there are many exampl of homosexualy nature, 's very mon. " Homosexual behavr has been observed black swans, pengus, sheep, and other animals, he '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.

WHAT DO IT MEAN TO BE GAY? DEFN AND MEANG OF GAY
A higher pch, wir pch range, longer vowels, expand vowel space, and more precise pronunciatn are voice characteristics associated wh gay men. Scientists hypothized that bisexual men’s voic might be nsired more feme-soundg than straight men’s and more mascule-soundg than gay men’s when me to self-reported and observer-reported masculy and femy.
One hundred sixty participants, divid evenly between men and women, were asked to listen to voice sampl om 60 men (divid evenly between gay, bisexual, and straight men). They rated the voic on a sle of zero (exclively heterosexual) to ten (exclively homosexual). 62% of the participants uld distguish between a gay man’s and a straight man’s voice.
Instead, their voic were rated more mascule than both straight and gay men’s voic.
