No individual gene alone makes a person gay, lesbian or bisexual ; instead, thousands of genes likely influence sexual orientation, a massive new study of the genomes of nearly half a million people suggests. The biological factors that contribute to sexual orientation are largely unknown, but many scientists suspect that genetics plays a role, given that same-sex sexual behavior appears to run in families and is seen more often in identical twins than in fraternal twins. Same-sex orientation remains criminalized in more than 70 countries, some with the death penalty, often stifling those willing to disclose such personal information. The new study, however, included a much larger number of participants, making the results more statistically reliable than those of the previous, smaller studies. In the largest genetic study of sexual orientation to date, scientists studied a group of about , volunteers in the United Kingdom and the United States who reported on whether they had ever engaged in same-sex sexual behavior. They relied on genetic data from the UK Biobank a long-term health and genetics study running in the United Kingdom and 23andMe, as well as responses to surveys asking questions about sexual identity, attraction, fantasies and behavior.
