| Abstract: | The karyotypes and Ag-NORs of Rhacophorus. nigropunctatus and Paa. yunnanensis were investigated. The results demonstrate that Rhacophorus. nigropunctatus had 2n=26=20m 4sm(5 8), with NF=52,in which, the secondary constritions have been observed in the arm of chromosome No.8,10, a Ag-NOR is located on the secondary constriction of No.10. Paa. yunnanensis had 2n=64, with NF=64, the all chromosomes are telocentric, and the secondary constriction locates on the chromosome No.10, it is heterotype. And the karyotypes of Rhacophorus. nigropunctatus were compared with the other relative species of Rhacophorus. |
