While common in plants, whole genome duplication, or polyploidy, is rare in animals. The animals that are polyploid tend to reproduce asexually. Notable exceptions in the amphibian world that display both polyploidy and sexual reproduction, include members of the Xenopus genus and Bufotes viridis complex. Novikova et al. (2020) investigated another system in the Australian genus Neobatrachus, where six members are diploid and three are tetraploid, to better understand the evolutionary role of polyploidism. They found asymmetric gene flow from the more isolated diploid species to tetraploids, which have wider distributions, as the origin of the polyploid species. Furthermore, these inter-specific hybrid tetraploids displayed more wide-spread gene flow and were more tolerant of climate-induced habitat loss, providing a potential rescue effect to species diversity in the genus.
