Localization of NORs in karyotypes of four Rana species

Abstract

NORs were localized by Ag-AS-staining in karyotypes of Rana nigromaculata, R. macrocnemis, R. latastei (2n=26) and R. chensinensis, 2n=24. As in the majority of other Rana species, the NORs are located in the long arms of the 10th (or 11th in R. chensinensis) chromosome pair. The presence of a second secondary constriction in R. latastei, as reported earlier, was not confirmed.
