Chromosomal banding properties of Oxynoemacheilus simavicus (Balık & B?n?rescu, 1978) (Teleostei: Nemacheilidae) from Gediz River (Turkey)

Abstract

The chromosomal banding properties of Oxynoemacheilus simavicus (Balık & B?n?rescu, 1978) were revealed out by C-banding and silver staining. Constitutive heterochromatin regions were determined on the pericentromeres of most chromosomes by C-banding. Otherwise, nucleolus organizer regions (NORs) were observed on the short (p) arms of one middle-sized submetacentric (sm) chromosome pair by silver staining. Also, Ag-NOR size and number polymorphisms were observed. The obtained results shall contribute to the genus Oxynoemacheilus chromosomal studies.
