Chromosomal Analysis of Oxynoemacheilus atili Erk’akan, 2012 (Teleostei, Nemacheilidae)

Diploid chromosome number, chromosome morphologies and chromosomal band properties (with C-banding and AgNOR staining) of endemic Oxynoemacheilus atili Erk’akan, 2012 were revealed out from Beyşehir Lake Basin, Turkey.Metaphase chromosomes were obtained from kidney cells. Diploid chromosome number was found as 2n = 50 andchromosome morphologies were as follows: five pairs of metacentric, nine pairs of submetacentric and 11 pairs of subteloacrocentric chromosomes. Fundamental arm number was calculated as 78. Constitutive heterochromatin regions weredetermined on the centromeres of chromosomes. NORs were detected on one pair of chromosomes. The obtained results maycontribute to nemacheilid chromosomal studies.
