Cytogenetic Analysis of Garra variabilis (Heckel, 1843) (Pisces, Cyprinidae) from Savur Stream (Mardin), Turkey
Abstract
In this study cytogenetic analysis were carried out on Garra variabilis (Heckel, 1843) individuals from Savur stream (Mardin). The karyotype of Garra variabilis was analyzed using G-banding, C-banding, Ag-NOR staining and Q-banding techniques. Diploid chromosomes number of specimens was determined as 2n=102. However, two karyotype formulae were identified in the G. variabilis specimens: female 42m+18sm+24st+18a (FN = 186) and males 41m+18sm+24t+19a (FN = 185). Nucleolar organizer regions (NORs) were identified by silver nitrate staining. NOR regions were observed on many chromosome pairs. The largest chromosome pair was defined as submetacentric. The detail karyotype of G. variabilis is reported for the first time.
