Abstract:   (6132 Views)
Karyotype of river loach Turcinoemacheilus kosswigi from the Euphrates River, Turkey was investigated using conventional Giemsa-staining and C-banding. Two females and two males were analyzed. Diploid chromosome number was 2n= 50 in all specimens. The karyotype consisted of four pairs of metacentric (m), seven pairs of submeta (sm)-subtelocentric (st) and 14 pairs of acrocentric (a) chromosomes, the number of chromosome was NF= 72. No heteromorphic sex chromosomes were found. C-banded positive constitutive heterochromatin was found in the entire short arms of a pair of large m-sm chromosomes and in the centromeres of several chromosome pairs though to a lesser extent. Karyotype and C-banding patterns of T. kosswigi were compared with those of other loaches.
Keywords: Balitorid loaches, Chromosome banding, Cytotaxonomy, Fish cytogenetics
