Abstract :The chromosomal banding properties of Oxynoemacheilus simavicus insert ignore into journalissuearticles values(Balık & Bănărescu, 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 insert ignore into journalissuearticles values(NORs); were observed on the short insert ignore into journalissuearticles values(p); arms of one middle-sized submetacentric insert ignore into journalissuearticles values(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.
Keywords : Chromosome, constitutive heterochromatin region, nucleolus organizer region
