title: [Stability of the population variants of the B-chromosome system in the East-Asian mouse Apodemys peninsulae from the Baikal region and northern Mongolia].
abstract: Analysis of the B-chromosome frequency and morphotypes in 160 mice Apodemus peninsulae from 17 localities of the Baikal region, Northern Mongolia, Trans-Baikalia, and the Russian Far East showed that the mice were from five geographical populations. The interpopulation difference was determined by variations of 0-4 macro B chromosomes and 0-11 micro B chromosomes. The B-chromosome number and morphotypes proved to be stable over the past 30 years in the geographical populations under study.
