Instead, a person's attraction to those of the same sex is shaped by a complex mix of genetic and environmental influences, similar to what's seen in most other human traits, researchers report. That's not in anyone's interest. The international study focused on the genetic profiles of nearly , people from the United States and the United Kingdom, a group approximately times larger than any previous study of the link between genetics and same-sex attraction, said lead researcher Andrea Ganna, a research fellow with the Massachusetts General Hospital's Analytical and Translational Genetic Unit.
