Sex and the single gene: New research shows a genetic 'master switch' determines sex in most animals
In humans and other animals, sex is usually determined by a single gene. However, there are claims that in some species, such as platyfish, it takes a whole "parliament" of genes acting together to determine whether offspring ...
