Scientists believe they may have discovered two ‘gay genes’
US scientists have reportedly found so-called ‘gay genes’ that may dictate sexuality in men.
Scientists have been searching for a so-called ‘gay gene’ and studying how sexual orientation is partly biologically determined, the New Scientists reports. Now, a new study has identified what might be two genes which have an impact on someone’s sexuality.
The study, carried out by Alan Sanders and his team at North Shore University, Illinois, compared DNA from 1077 gay and 1231 straight men.
They scanned participants’ genomes to look for differences in their DNA sequences to find genes whose variants may link to sexual orientation.
The first gene found, called SLITRK6, sits on chromosome 13 and is an active part of the brain called the diencephalon, the same region of the brain that contains
