New data on the karyological variability of Apodemus peninsulae mice (Thomas, 1906) in the Tyva Republic are presented. By the ratio of macro and micro B chromosomes in the mice we studied earlier in this region and in the present study, it became possible to isolate several geographical populations that combine a number of studied catch points of East Asian mice within the territory of the Yenisei River basin in the northern and southern directions from Kyzyl (Republic of Tyva). The frequency distribution of micro B chromosomes makes the most significant contribution to obtaining a differentiation pattern of populations of mice with B chromosomes by area.
