A new explanation for evolutionary changes in genetic sex-determination systems

...autosome, a non-sex-chromosome, that then invades to become a new sex chromosome. The mechanism suggested by these authors begins with an autosome that carries two genes with particular features. One of these two genes is under sexually antagonistic selection. This means that some versions of t...
