A new karyotype and chromosomal banding pattern in Nannospalax ehrenbergi (Nehring, 1898) (Rodentia: Spalacidae) from southeast Anatolia, Turkey

This paper presents new data on chromosomes of the Palestine mole rat, Nannospalax ehrenbergi, from southeast Anatolia, Turkey. A new chromosomal form, 2n = 56, NF = 62 and NFa = 58, is determined from the region. C-banding revealed pericentromeric constitutive heterochromatin in one submetacentric and seven acrocentric autosome pairs. Two acrocentric autosome pairs and an acrocentric chromosome with a secondary constriction showed interstitial C-positive bands on their long arms. A secondary constriction was detected in the Y chromosome. The NORs were observed in one medium-sized metacentric autosome pair, and in four acrocentric pairs of autosomes.
