[Genetic variability and the origin of house mouse from the territory of Russia and neighboring countries].

Genetic differentiation and gene geographic variation of house mouse from the territory of Russia and neighboring countries was examined based on the allozyme analysis of samples from natural, semisynanthropic, and obligate synanthropic populations. The results of analysis of genetic differentiation, performed using 22 interpreted loci, as well as the data on gene geographic variation of four allozyme markers (Idh-1, Sod-1, Aat-1, and hemoglobin) validated the hypothesis on rapid mice expansion from the south of Eastern Europe to the Pacific coast of Asia. It was demonstrated that moving eastwards led to the formation currently expanding zones of hybridization between the "northern" M.

[Discordance in the distribution of markers of different inheritance systems (nDNA, mtDNA, and chromosomes) in superspecies complex Mus musculus as a result of extensive hybridization in Primor'e].

The genetic structure of eight Mus musculus L. populations in Primorskii krai was studied with the use of taxon-specific markers of different inheritance systems: nDNA (RAPD), mtDNA (D-loop), and chromosomes. The results obtained demonstrate that although the compared nuclear marker characteristics (nDNA and chromosomes) have the same basis they are not linke with each other and, moreover, are often mutually inconsistent.

[Variability of chromosome 1 with HSR insertions in natural and synanthropous populations of house mouse Mus musculus L. 1758].

House mice carrying aberrant chromosome 1 with an insertion of homogeneously stained regions (HSR) have been studied. The mice were collected in the North Caucasus, Chita and Amur oblasts, Spitzbergen and Kunashir Islands, Altai krai, Khabarovsk krai, Primorye, Sakhalin, Kamchatka, Turkmenistan, and Kazakhstan. In these mice, the aberrant chromosomes were assigned to the "Asian" type, i.

[Genetic studies of house mice from the hybrid area of the Primorskii Region].

Cytogenetic and allozyme differentiation of house mice Mus musculus L. was studied in 21 samples of Primorskii krai (region) from 1984 to 1998. The use of Q-H- and C-banding made it possible to reveal a high variation in the content and distribution of pericentromeric heterochromatin and high frequencies of marker autosomes 5, 7, 10, 12, 15, and 17-19 in the karyotypes of mice from some samples.
