  • The comparative karyological analysis of the Korean treefrogs, Hyla japonica and Hyla suweonensis, were performed by C-banding method. Heteromorphic sex chromosomes, female heterogamety, has been identified in the 3rd chromosomes of H. suweonensis H. suweonensis seem to have sex chromosomes which are Zz/ZW type. The Z chromosomes contain large amount of constitutive heterochromatin, but little heterochromatin is located in the W chromosomes. This is in contrast to all previously known amphibian and most other vertebrate's W or Y chromosomes, except Gastrotheca oui'ern and G. walken (Schmid et al., 1988).
