title: [Variability of the cytogenetic structure of Apodemus peninsula (Rodentia, Muridae) population from the West Sayans region].
abstract: Karyological investigations of East-Asiatic mice (28 animals) from 5 catching points in the region of West Sayans revealed the presence of 1-12 B-chromosomes in these animals. Nearly all the mice had their individual variant of B-chromosomes system, including combinations of two-shoulder-like chromosomes of different size (from 1 to 5), and also small acrocentric (from 0 to 1) and dot-like B-chromosomes (from 0 to 9). Most frequent were the mice with 5 and 6 (21%) B-chromosomes. The catching points were 120 kilometers from each other, and clinical changes were observed between these points in the direction from the South to the North.
