what makes a child gay

Theory: Lbians get om their fathers, gay men om their mothers.

SCIENTISTS MAY HAVE FALLY UNLOCKED PUZZLE OF WHY PEOPLE ARE 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.

IS YOUR CHILD GAY?

"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.
