[Genetic differentiation of house mice in the south of the Soviet Far East].

Electrophoretic analysis of 24 loci specifying a number of enzymatic and non-enzymatic proteins was carried out in populations of Primorye house mice. No variability in Ldh-B, Ldh of testis, fumarase, alpha-Gpd, Aat-2, Sod-2, Gp-1, GP-3 was found. Distribution of the same main variant in all samples is represented by Sdh, Mor-1, Mor-2, Ldh-A, GP-2, Est-D, Gpd-x, Pgl, Ldr and alb. The second variant of these loci was found in one or two animals. Two and more variants encountered with significant frequency were detected for Id-1, Hbb, Aat-1, Est-1, Est-2, Mod-2. Hybrid origin of the Primorye house mouse is assumed. Genogeography of Id-1, Hbb, Aat-1 and Est-1 points to involvement of the Mus-2C castaneus form in development of their gene pool, the effect of Mus-2A musculus being not excluded. Genogeography of Sod-1 confirms the involvement of both castaneus and musculus. Intensive mutual penetration of these forms (more than 300 km from north to south) indicates that they did not achieve the level characteristic of musculus and domesticus in the course of their differentiation.
