Using a big-data technique called genome-wide association, the researchers estimated that common genetic variants — single-letter differences in DNA sequences — account for between 8 percent and 25 percent of same-sex sexual behavior. Rather, their findings paint a diverse and complex picture of human sexuality, and the genetic factors that influence it.
