Review of the results of the study of genetic-demographic processes in the population of the three biggest megalopolises of Russia: Moscow, Saint Petersburg, Novosibirsk, and the capital of Republic of Belarus – Minsk is presented. By the survey and census data of the population of megalopolises, the main genetic-demographic parameters are calculated. Data on migration of population and parameters of marriage structure are provided. The analysis results of uneven settlement of ethnic groups and estimates of ethnic diversity, and, also, selected maps reflecting ethnic topography of the population of megalopolises are presented. In the male population of the studied megalopolises, peculiarities of distribution of haplogroups of Y-chromosome in connection of migration are revealed. In the population of megalopolises, necessity of developing genetic data bases and, also, reference data bases for the goals of medical genetics and criminalistics taking in consideration complexity and dynamism of population structure under action of genetic-demographic processes is justified.
