Abstract

This roundtable analyzes the first genome-wide association study (GWAS) that sought to identify the genetic variations that correlate with same-sex sexual behavior. Drawing on over 450,000 individuals’ genetic material from the UK Biobank and 23andMe, the 2019 study concluded that “many loci with individually small effects,” which are spread across the entire genome, contribute in statistically significant but highly unreliable ways to an individual's sexual behavior. The study was thus greeted by geneticists, science journalists, and even some LGBTQ+ advocates as heralding the demise of the mythical “gay gene.” However, the study itself did not drive a stake through the heart of the “born this way” idea. In fact, the researchers framed their efforts as having revealed the “genetic architecture”—which is to say the blueprint or design—of same-sex sexual behavior. Stephanie Clare, Patrick R.
