Abstract
Highly differentiated ZZ/ZW sex chromosomes and an exceptionally low genome size were found in the karyotypes of Pyxicephalus adspersus (Anura, Ranidae). The W-chromosome is considerably smaller than the Z-chromosome and consists to a very great proportion of constitutive heterochromatin. The DNA content of this species and the chromosome length have the lowest values determined in the Ranidae to date.Entities:
