Karyotype analysis of ground squirrel (Mammalia: Rodentia) in Malatya (Türkiye)

Abstract

The study was carried out in order to determine chromosomal variations both within and between populations in Spermophilus in Malatya. By the analysis of karyotypes we obtained the diploid chromosome number 2n = 42 and NF = 68 and NFa = 64 of these one pair of chromosome was metacentric, seven pairs were submetacentric, four pairs were subtelocentric and eight pairs were acrocentric. The X chromosome was metacentric and Y was acrocentric. In the result it was shown that there was difference neither in the number nor in the morphology of the chromosomes both within and between populations. The results were compared with previous studies and the karyological and taxonomical status of Spermophilus were discussed. © 2006 Asian Network for Scientific Information.
