title: [Geography of genetic processes in the population: genetic migration in Northern Eurasia (Central Asia region)].
abstract: Based on the data of the census of 1970, a map of the rates of gene migrations in the rural population of Central Asia and Kazakhstan was drawn. The corrected average value for 35 populations of oblasts (administrative regions) and autonomous republics was m = 0.0606 +/- 0.0102. The estimate obtained from the mapped data was 0.0799 +/- 0.0014, which is 1.2-fold higher than similar values for Europe. The relationship between the rate of gene migration m, the genetically effective population size Ne, and the density of elementary populations in the studied area Pp was analyzed by means of correlation and regression analyses. The following relationship was obtained: m = A/Ne + BPp, where A > 0 and B < 0. This was accounted for by the fact that the migration flow is mainly directed to the less densely populated rural areas. Given that the region was chosen somewhat artificially, studying gene migrations in Central Asia and Kazakhstan as separate historical, geographic, and genetic subregions of northern Eurasia might be a better approach.
