DOI : 10.4194/1303-2712-v16_4_18 Viewed : 1147 - Downloaded : 895 The aim of this study is to reveal chromosomal properties of endemic Seminemacheilus lendlii fish species. Metaphase plates were obtained from kidney cells. The diploid chromosome number was observed 2n=50; consisting of eight pairs of metacentric, 10 pairs of submetacentric and seven pairs of subtelocentric chromosomes. The fundamental number of chromosomal arms (FN) was found as 86. Positive C-bands were seen on the centromeric region for several chromosomes. Also, heterochromatic blocks were determined on the short and/or long arms of some chromosome pairs. Four nucleolus organizer regions (NORs) were observed on the silver stained metaphase plates. This study may contribute to cytogenetic data of Anatolian loaches. Keywords : Anatolian loach, chromosome, karyotype, C-banding, nucleolus organizer region (NOR)
