Is Being Gay Genetic? - Dr. Christopher Yuan

Homosexuality genetic or choice - something is

Reading through this platform, I found an article entitled " Can homosexuals become Christians? However, his ending points dilute the whole message he intended to pass across. He uses his last paragraphs to make unjustifiable and false conclusions about homosexual persons and the whole other sexually queer groups Gay, Lesbian, Transgender, Bisexual and Intersex. I will not go into details about his argument for or against Christianity accommodating homosexual persons, but will deal with his ending points. The writer seems to be oblivious of the factual tenets that sorround the issue of homosexuality. He prescribes to the ignorant, yet dangerous, concept that "homosexuality is a choice. The same stereotype has mutated to prejudice and discrimination in many countries around the world. homosexuality genetic or choice.

Few aspects of human biology are as complex—or politically fraught—as sexual orientation. Now, a new study claims to dispel the notion that a single gene or handful of genes make a person prone to same-sex behavior.

The analysis, which examined the genomes of nearly half a million men and women, found that although genetics are certainly involved in who people choose to have sex with, there are no specific genetic predictors. Yet some researchers question whether the analysis, which looked at genes associated with sexual activity rather than attraction, can draw any real conclusions about sexual orientation. The handful of genetic studies conducted in the past few decades have looked at only a few hundred individuals at most—and almost exclusively men.

Other studies have linked sexual orientation with environmental factors such as hormone exposure before birth and having older brothers. In the new study, a team led by Brendan Zietsch of the University of Queensland, Australia, mined several massive genome data banks, including that of 23andMe and the UK Biobank 23andMe did not fund the research.

They asked more thanparticipants whether they had ever had sex with someone of the same sex, and also questions about sexual fantasies and the degree to which they identified as gay or straight. The researchers found five single points in the genome that seemed to be common among people who had had at least one same-sex experience. homosexuality genetic or choice

Two of these genetic markers sit close to genes linked to sex hormones and to smell—both factors that may play a role in sexual attraction. But taken together, these five markers explained less than 1 percent of the differences in sexual activity among people in the study. When the researchers looked at the overall genetic similarity of individuals who had had a same-sex experience, genetics seemed to account for between 8 and 25 percent of the behavior. The rest was presumably a result of environmental or other biological influences. The findings were published Thursday in Science.

Despite the associations, the authors say that the genetic similarities still cannot show whether a given individual is gay. The research has limitations: almost all of the participants were from the U. Still, researchers welcome the data.

The study will not be the last word on the vexing question of what causes homosexuality, however. In geneticist Dean Hamer of the U. But Hamer, now retired, disagrees.

His study, which analysed the genomes of 40 pairs of gay brothers, looked exclusively at people who identified as homosexual.]
