title: Recombination rate between sex chromosomes depends on phenotypic sex in the common frog.
abstract: 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.
