There Is No ‘Gay Gene,’ Study Finds
In a massive new study published yesterday in the journal Science, an international team of researchers said they discovered a number of genes that influence sexuality. But so does a person’s environment, making it “effectively impossible” to predict sexual behavior based solely on genetics. The survey of 470,000 mostly White British people of both sexes did, however, link same-sex sexual behavior with genes responsible for smell, male baldness and risk-taking.
How comprehensive was the survey? Experts say it’s limited because of its focus on people of European ancestry, but also noted that “it’s at least a first step.”
