[The dynamics of the allele variants of biochemical markers in generations of cattle in the exclusion zone of the Chernobyl Atomic Electric Power Station].

Analysis of the heritability of allelic variants of polymorphous genetic-biochemical systems in the cattle groups, reproduced in conditions of increased radionuclide pollution in exclusion zone of the Chernobyl AES was carried out. The disturbances of equal probability of the heritability for different allelic variants in some cattle group were revealed. It was supposed, that the appearance of the disturbances may take part in changeabilities of different gene pools under the conditions of ecological stresses. Possible mechanisms of this phenomenon were discussed.
