title: [Lactase deficiency among representatives of various nationalities of Siberia].
abstract: Some features of lactase tolerance were investigated in representatives of varying groups of indigenous population in Siberia-Mansi, Khanty, Nenets, Buryats. The indirect method was used to evaluate lactase activity. A total of 92 subjects were investigated. It was found that 32% of the representatives of the Urals population group and 53% of Buryats were capable of lactase assimilating. The data obtained correspond to the cultural-genetic hypothesis on the nature of lactase tolerance in the representatives of different ethnic groups.
