To ensure that their results are not misinterpreted, the study researchers worked with LGBTQ advocacy groups and science-communication specialists on the best way to convey their findings in the research paper and to the There s no one“ gay gene. Large-scale GWAS reveals insights into the genetic architecture of same-sex sexual behavior.
Neale and colleagues drew on data from nearly half a million people who submitted DNA samples to the genetic testing company 23andMe and the U. For instance, Ganna says that people who have exclusively same-sex or exclusively opposite-sex partners are genetically distinct from people who have partners of both sexes.
The small contribution of genetics to sexual behavior is in line with genetic contributions to other There s no one“ gay gene, such as level of education attainment. Close banner Close. But people tend to want black-and-white answers about complex issues.
Another gene was associated with male baldness, which is closely linked to how the body regulates sex hormones and might suggest a relationship between hormone regulation and same-sex desire, Ganna said.

All of the genetic variants the researchers identified together account for eight to 25 percent of the differences in same-sex sexual behavior. If lots of people with a trait in common also share certain SNPs, chances are that the SNPs are related in some way to that characteristic.
Hamer said. In a way, the range of opinions by scientists who also identify as L.
