A rapid rate of sex-chromosome turnover and non-random transitions in true frogs

A rapid rate of sex-chromosome turnover and non-random transitions in true frogs

The evolutionary forces that favour transitions in sex chromosomes are not well understood. Here, Jeffries and colleagues show a very high rate of sex chromosome turnover in true frogs, which may be driven by rapid mutation-load accumulation due to the low recombination rate in males.
