Cytogenetic characteristics of endemic Squalius cappadocicus Özuluğ and Freyhof, 2011 in Türkiye

In this study, a detailed chromosome analysis of the endemic Cappadocian Chub, Squalius cappadocicus in Melendiz Stream (Aksaray) was performed. The standard Giemsa staining, C-banding (CBG and CB-DAPI), Ag-NOR technique were applied. diploid number 50; its karyotype formula 14M + 16Sm 10St 10A. Heteromorphic sex chromosomes weren’t detected studied specimens. all chromosomal arms (NF) 90. C-banded CB-DAPI species, dark C-bands observed centromeric region some bi-armed acrocentric chromosomes, while slightly or pericentromeric chromosomes. Three different active Ag-NORs, which hemizygous, samples examined. Two these NORs other short arm. species evaluated as feature that distinguishes it from Türkiye.
