The karyotype of the specimens from Ankara and Cankiri provinces consist of 2n=38, NF=60 and NFa=58 while the karyotype of Kirikkale specimens consist of 2n=38 and NFa=59 due to a heteromorphic autosome pair. The X is a large to medium sized acrocentric and the Y chromosome is a small acrocentric in all examined specimens. Constitutive heterochromatin is located in the centromeric regions of all pairs of autosomes and the X chromosome. Nucleolar organizer regions (NORs) are located only in 3 autosome pairs.eninfo:eu-repo/semantics/closedAccessRoof ratC-bandingAg-NOR bandingkaryotypeCentral AnatoliaArticle591-2313410.3409/fb59_1-2.31-342-s2.0-7925164372621614964Q4WOS:000286695100006Q3
