The More Older Brothers You Have, The More Chances You Are To Be Gay. Now We Might Finally Know Why




Dr Nina McCarthy, from the University of Western Australia's School of Biomedical Sciences, said it's unlikely a "gay gene" would ever be discovered, as it's more likely homosexuality is a result of a combination of biological and environmental factors. "The justification for the research is unclear to me," she said, explaining that similar studies are often carried out to try and find a cure for an illness.
"As homosexuality is emphatically not an illness, the potential benefits of trying to better understand the underlying biology of homosexuality remain (to me) a little elusive." The study released last week has also been criticised for having a small sample size, of around 2000 participants compared to similar genome studies with more than 100,000 participants.
