Ag-NOR karyotypes of five endemic pseudophoxinus bleeker, 1860 (Teleostei: Leuciscidae) species from anatolia

Abstract

This study presents Ag-NOR (silver-nucleolus organizer region) karyotypes of five endemic Pseudophoxinus species from Anatolia. The specimens were collected from central and southern Anatolia. The collected specimens were carried alive to the laboratory. Chromosome slides were prepared and Ag-staining technique was applied. Ag-NOR metaphases were photographed with a camera-equipped light microscope. Karyotypes of this metaphases were arranged. Ag-NORs were distributed between the second and eighth submetacentric chromosome pairs in the studied species. This study reveals the details of the Ag-NOR distributions on the karyotypes and may improve the cytogenetic data of the genus.
