Editor's note

For decades geneticists have tried to work out whether there is a “gay gene”. Now the largest ever study – involving genetic information from almost half-a-million people – reveals there are likely to be many genes that influence same-sex behaviour, rather than just one.

Researchers led by Brendan Zietsch of the University of Queensland compared people’s genetic makeup with their sexual behaviour and identity. They found hundreds of places in the DNA sequence that seem to influence same-sex attraction.

As Zietsch explains, the biology involved is so complex we still can’t predict a person’s sexuality based purely on their genes.

Given the unique aspects of the proposed bill, there should be a longer consultation period to examine why religious freedoms should be prioritised over other freedoms.
