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 researchers found five single points in the genome that seemed to be common among people who had had at least one same-sex experience. 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. “It’s the end of the ’gay gene,’” says Eric Vilain, a geneticist at Children’s National Health System in Washington, D.C., who was not involved in the study. the new study is the final nail in the coffin for Xq28 as a cause of same-sex attraction.

This whole LGBT noise is just a distraction. If you are a good person, behave good to the people, or life or things coming infront of you. Thats the correct solution for all the identity politics.
