Hybridization and polyploidy in the weeping lizard Liolaemus chiliensis (Squamata: Liolaemidae)

In reptiles, polyploidy is an unusual phenomenon that can originate from interspecific hybridization. In Chile, the lizard Liolaemus chiliensis provides a unique model with which to study the origin of polyploidy because it occurs in populations of diploid individuals and a few populations that also contain triploid and diploid–triploid mosaic lizards. To test whether L. chiliensis polyploids were hybrids between lineages within the species, we...
