[Population genetics study of the functional asymmetry of the brain in native and migrant population of the north-eastern USSR].
It is shown that ethnic groups of the North-East of the USSR (eskimos, coast and reindeer chukchi, koryaks and evens) differ significantly in phenotype frequencies of hemisphere interrelations, and the extent of differences conforms to non-similarity of the cultural and economic structure of these populations. Significant phenotype frequency dynamics observed in new-coming population, depending on the duration of dwelling under the North conditions, makes the phenotype of "long-livers" of the North more distant from the population of middle latitudes and closer to the aboriginal populations. Such a dynamics of phenotypic structure of new-coming populations is due to selective migration of the population. Great adaptability of the right hemisphere relationship type individuals of aboriginal as well as new-coming population to the North-East conditions is grounded. The role of hemisphere relationship type in adaptation to the environmental conditions is under discussion.
