[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. The presence of marker alleles that are typical of the subspecies groups castaneus and musculus was shown for protein loci Idh, Sod-1, Aat-1, and Hbb. The data obtained indicate that the fauna of house mice of Primorye is characterized by subspecific mosaicism and hybrid origin. Apparently, subspecies M. m. castaneus, M. musculus ssp., M. M. homourus, and M. m. gansuensis contributed, to different degrees, to the formation of this fauna.
