We show that the recombination rate between the sex chromosomes is controlled by phenotypic, rather than genotypic, sex in sex‐reversed common frogs. This supports the recent hypothesis that in ectothermic vertebrates sex reversal can prevent the progressive accumulation of mutations to nonrecombining Y chromosomes and their subsequent evolutionary decay.
