The karyotype of Apodemus agrarius (Pallas, 1771) (Mammalia: Rodentia) in Turkey

Abstract The karyotypes of seven specimens of Apodemus agrarius from Igneada in Thrace (European Turkey) were examined. The results showed that the diploid number of chromosomes is 2n = 48, the number of autosomal arms NFa = 56, and the fundamental number NF = 58. The X chromosome is large acrocentric and the Y chromosome is small acrocentric. It was found that one subtelocentric pair in the chromosome set of A. agrarius is different from that of European populations.
