The polytypy of 46-chromosomes karyotypes determined by the sites of interstitial telomeric sequences (ITS) and ribosomal DNA emphasizes the genetical isolation of M. arvalis s.s. and M. obscurus. Key words:  FISH, chromosomal DNA markers (ITS, rDNA), sibling species, common voles |  Back   |  Contents   |  Main  |
