The gene pool of the Belgorod oblast population : malecot’s isolation-by-distance parameters

Abstract

The mean distance between birthplaces of spouses (у, у '), the proportion of medium migrations (k), and the effective migration pressure (Me) have considerably increased, and the linear systematic pressure coefficient (b) has decreased in the human population of the Central Chernozem region during the past 50 years. However, the local inbreeding level (a), which is determined by both an increase in the migration intensity and a decrease in the effective population size (Ne), has remained practically unchanged
