All-male hybrids of a tetrapod Pelophylax esculentus share its origin and genetics of maintenance

ConclusionsOur results confirm that also males can perpetuate over many generations as the unisexual lineage and successfully compete withP. ridibundus males for eggs provided byP. ridibundus females. Natural persistence of such sex-specific hybrid populations allows to studying the similarities and differences between male and female reproductive parasitism in many biological settings.
