No single ‘gay gene’, reveals the largest-ever study of the genetics of same-sex sexual behaviour

ABC news, 30/08/2019

Scientists have again debunked the idea of a single “gay gene”, in the largest study to date of the genetics of same-sex sexual behaviour.

Rather, their findings paint a diverse and complex picture of human sexuality, and the genetic factors that influence it.

Nearly half a million people took part in the study, mostly from the United Kingdom and the United States, which was published in the journal Science today.

How we inherit masculine and feminine behaviours: a new idea about environment and genes

What if thousands of years of gendered environments actually reduced the need to develop genetic mechanisms to ensure gender differences? This is the idea we suggest in our new paper.

Advances in evolutionary biology recognise that offspring don’t just inherit genes. They also reliably inherit all kinds of resources: a particular ecology, a nest, parents and peers. And it appears that these stable environmental factors can help ensure the reliable reproduction of a trait across generations.

Born this way? An evolutionary view of ‘gay genes’

The claim that homosexual men share a “gay gene” created a furore in the 1990s. But new research two decades on supports this claim – and adds another candidate gene.
