title: [Polymorphic biochemical systems in the population of immigrant inhabitants of the northeastern USSR. II. Genotypic distances between groups of persons with a varying duration of living under extreme environmental conditions].
abstract: Analysis of the differences in the groups examined for phenotypes and genes has shown that the longer dwelling in the regions of the extreme conditions, the greater changes are in the genetic structure of separate selections with "retreating" from middle latitudes'population and "approaching" the aboriginal one of the North-East. This "dynamics" is mostly pronounced in men and groups characterized by very long dwelling in the region; the differences between representatives of both sexes are maximal. A slightly more isolated position is occupied by the genetic structure of individuals living in the North from the birth. The data obtained allow to assume that the genetic structure of the man's population being formed in the extreme conditions, tends to the ecological fit on account of the selectivity of migratory behaviour. The ecological fit of separate genotypes may well be assumed to be different for representatives of both sexes and on different stages of ontogenesis.
