[Comparative study of the variability of morpho-physiological traits and polymorphic genetic markers in migrant and local Russian population of the Western region of the Baikal-Amur railway].

Morpho-physiological traits and variation of gene markers of 119 complete families from Russian migrant population inhabiting the Western area of Baikal-Amur Railway and 92 such families from Russian native population from the same area were compared. In migrant women body length was 2 cm higher and age of menarche was 8 months earlier than in native population. Average values of 5 anthropometric measurements of newborns in migrant population were higher than in native population. No significant differences in gene frequencies of 9 blood groups and proteins between these groups were found. Marked deficiency of observed heterozygosity (11%) was found in native population as consequence of the genetical drift.
