Karyological analysis of endemic Pseudophoxinus anatolicus (Hankó 1925) in Türkiye

Abstract

The karyological characteristics of nearly half of the Pseudophoxinus species in Türkiye were determined. In this study, it is planned to determine the karyological characteristics of P. anatolicus, which is common in Beyşehir Lake, specimens were caught from the coast at Çiftlik village. The captured specimen were karyological analysed and Giemsa staining, C-banding and Ag-NOR staining were applied to the slides that obtained. The chromosome set of this species consists of 12 pairs of metacentric, eight pairs of submetacentric, two pairs of subtelocentric and three pairs of acrocentric chromosomes. Dark and slightly C-bands were observed in the centromeric regions of some chromosomes. Active Ag-NORs were detected in the telomeric region of the short arm of two pairs of chromosomes. Our results are similar to those of other Pseudophoxinus species except for some differences and it was determined that Anatolian minnow has a conserved karyotype like other Pseudophoxinus species.
