[Populational-age dynamics of types of haptoglobins among the inhabitants of the northeast USSR]. 1977

L L Solovenchuk, and G P Avanesova

As the result of investigation of the types of haptoglobin in 367 practically healthy inhabitants of Magadan and of 711 Chukchees from four villages of the Chukotsk National Region an increase of the frequency of the 1--1 type in each successive age group was observed. In Chukchees in elder age groups it is less conspicuous. A different adaptive value of the types of haptoglobin in the region studied is assumed. This adaptive value can be expressed as follows: 1--1 greater than 2--1 greater than 2--2. A consideration is adduced about the presence of this region of a powerful systematically acting factor leading to a simple shift of the frequencies of haptoglobin types in respresentatives of two ethnic groups. A conclusion is drawn about an unequal adaptive value of haptoglobin types at different periods of ontogenesis.
