Bu çalışmada, Güentheri tarla faresi (Microtus guentheri), Kısa kulaklı kır faresi (Microtus majori) ve Yaygın tarla faresi (Microtus arvalis) türlerinin standart karyotipleri ve kromozomların C-bant özellikleri belirlendi. M. guentheri türünün diploid kromozom sayısı (2n) = 54 ve otozomal kromozomların kol sayısı (NFa) = 52, M. arvalis (obscurus sitotip) türünün 2n = 46 ve NFa = 68, M.majori türünün 2n = 54 ve NFa = 56 şeklindedir. M. guentheri otozomal ve eşey kromozomlarda pericentromerik C-bant olduğu belirlendi. Microtus arvalis (obscurus sitotip) ve Microtus majori karyotiplerinde otozomal kromozomlar C bant pozitif ve negatif şeklindedir. M. arvalis türünde X ve Y kromozomu C bant negatif özelliktedir. M. majori karyotipinde X kromozomunun uzun kolunda sentromerden telomere doğru genişlemiş heterokromatin blok bulunmaktadır. Y kromozomu ise tamamen heterokromatindir.

Conventionally stained and C- banded karyotypes of Guenther’s vole (Microtus guentheri), Major's pine vole (Microtus majori) and Common vole (Microtus arvalis) were studied from Turkey. Diploid chromosome numbers of M. guentheri, M. arvalis and M. majori were found as 2n=54 and NFa=52, 2n=46 and NFa=68 and 2n=54 and NFa=56, respectively. All chromosomes of M. guentheri were pericentromeric C- band. In Microtus arvalis (obscurus cytotype) and Microtus majori karyotypes, autosomal chromosomes were heterochromatin C band positive and negative band. In M. arvalis (obscurus cytotype), sex chromosome was C band negative. In this study, heterozygote chromosome was not found in the obtained autosomal chromosome set of M. arvalis. M. majori has enlarged heterochromatin block from centromere to telomere on the long arm of X chromosome. Y chromosome was completely heterochromatin.
