Abstract
The karyotypes of 95 individuals (57 males and 38 females) of the yellow-throated mouse (Sylvaemus flavicollis Melchior, 1834), caught at seven points in Eastern Europe, were studied. Only one individual had one extra chromosome. It was shown that in Sylvaemus flavicollis in the surveyed sites from the central part of the range (Eastern Europe), the frequency of occurrence of individuals with B chromosomes is very low and probably does not depend on the ecological conditions of habitats.
