His comments speak to the larger narrative about using biology to define complex behaviors — like sexuality — when science is always evolving and takes time to find anything close to definitive. View our privacy policy.

Hamer said. Dean Hamer, a former National Institutes of Health scientist who led the first high-profile study identifying a genetic link to being gay insaid he was happy to see such a large research effort.

He and others noted that older participants came of age when homosexual behavior was criminalized in Britain and that for much of their What do the new ‘gay genes’ tell us about sexual homosexuality was classified as a psychiatric disorder.

Biological factors shape sexual preference. The team then looked at which genetic variants might be behind the link, using data from more than , participants in the UK Biobank project and more than 68, individuals whose data was collected by the company 23andMe.

The Latest. Rahman added he was not surprised that the genetic variants identified only have small individual effects, pointing out that since same-sex behaviour is linked to having to fewer offspring, evolution is likely to hide such variants in effect.
