As a sexual orientation, homosexuality is "an enduring pattern of emotional, romantic, and/or sexual attractions" to people of the same sex. Genetics plays a role in male sexual orientation but social and environmental factors are also involved, research suggests. There is no study on homosexuality that has been done where the researcher has claimed to have found a genetic cause, only postulations. Eight major studies of identical twins in Australia, the U.S., and Scandinavia during the last two decades all arrive at the same conclusion: gays were not born that way. I n 1993, researchers discovered a stretch of DNA on the X chromosome they believed to be linked to male homosexuality. There have been studies suggesting that there is a genetic element to homosexuality in women, but more research has been done in men, says Sanders. The term gay is a synonym for homosexual, which is defined as, 1,2 "Of, pertaining to, or exhibiting sexual desire or behavior directed toward a person or persons of one's own sex." Is homosexuality genetic or the result of upbringing? The Gay Gene What causes homosexuality? Their hypothesis: if homosexuality is an inherited trait, then more twin brothers would be expected to have the same orientation than non-twin or non-biological brothers. Are people 'born that way' or 'made that way by men'? Twin studies suggested, moreover, that gene sequences can't be the full explanation. Homosexuality is romantic attraction, sexual attraction, or sexual behavior between members of the same sex or gender. The belief that homosexuality is "genetic" tends to translate into a more positive attitude toward it. It is hard to say because he does not want to reveal. Homosexuality may be triggered by environmental factors during childhood after scientists found that genetic changes which happen after birth can determine whether a man is straight or gay. young ppl (13-18) is being gay a choice????

However it is 100% sure he likes men. I understood I am bi when I was 12 years old. I N 1993 A region of the human genome called Xq28 was linked to male homosexuality, and the controversial notion of a “gay gene” was born. After 2 years from this moment. How is it possible that I could inherit this? Opinions differ widely among leading researchers. Similarly, the carrier of homosexuality is determined by a number of genes and each of … Scientists say they have shown how male homosexuality could be passed from generation to generation. It’s the year 2015 and the talk of homosexuality is still a controversial topic. The results suggest that several genetic regions may influence homosexuality. But it’s not. Genetics cannot tell "the whole story," as Eric Vilain, director of the Center for Genetic Medicine Research at Children’s National Health System, … Their Reported Findings. It is widely believed that the public will become more accepting of homosexuality if they are convinced that it is inborn and immutable. Is it possible? Homosexuality: genetic/environmental, choice/no choice? Why it shouldn't matter Scientific models indicate that while the variation of sexual orientation may not be strictly a matter of having a certain kind of gene, the manner in which certain genes are expressed is almost certainly responsible for homosexuality. Attempts to find a "gay gene" have never identified any gene or gene product that is actually associated with homosexual orientation, with studies failing to confirm early suggestions of linkage of homosexuality to region Xq28 on the X chromosome. In short, concerning homosexuality and genetics, science has yet to find a link in terms of it being a cause of homosexuality, although a common argument is that an inclination to homosexuality is inborn and immutable. For example, the identical twin of a gay man, despite having the same genome, only has a … How homosexuality is 'inherited' Campaigners object to gay being labelled a lifestyle.

Nature encourages mothers to pass on a "gay trait" to their male offspring by boosting their fertility, the Italian University of Padova team believes. Hamer began his painstaking search for a genetic contribution to sexual behavior by studying the rates of homosexuality among male relatives of seventy-six known gay men. My mom told me that my father is bi or gay. Is it biological or psychosocial? There is NO such thing as a single 'gay gene': Scientists find homosexuality is likely caused by a combination of environmental and genetic factors. Homosexuality is probably epigenetic, rather than genetic. They found that homosexual men shared genetic markers in a region of chromosome 8, and the Xq28 region of the X chromosome. Complex science surrounding genetics and homosexuality L e t t e r s There is no simple dichotomy between genetic and environmental control of a trait, say Brian and Deborah Charlesworth . The largest-ever study of genetics and sexual orientation offers a theory about the longevity of genes that influence homosexuality. Those research findings have … Homosexuality can refer to both attraction or sexual behavior between people of the same sex, or to a sexual orientation. A genetic analysis of almost half a million people has concluded there is no single "gay gene". Homosexuality - biological, or a choice? I didn’t show that gay men are ‘born that way,’ [which is] the most common mistake people make in interpreting my work.” 'Not everyone is interpreting the fact that there’s no single ‘gay gene’ the right way.'

There's no such thing as a single "gay gene" that drives a person's sexual behavior, concludes the largest genetic study ever conducted on the issue. Research has not produced a 100% result of their findings. As per the studies, homosexuality may be due to heredity, but the cause also includes developmental component. When we come to the discussion of genes and traits, one thing we must know is, one single gene can affect one or even more traits and one single trait can be affected by one or more genes. In some societies, homosexuality is accepted, in others, it is frowned upon but tolerated, in yet others, it is a serious criminal offense, possibly punishable by death. If my dad was bisexual how likely am I to have gay sons? New study finds there is no "gay" gene 04:05. Genetic analysis of behavioral differences among human beings requires both careful experimental design and appropriate genetic models. “At best genetics is a minor factor,” says Dr. Neil Whitehead, PhD.
