Karyotypic instability of reindeer in zones of potential environmental problems

The problem of livestock breeding in areas adjacent to industrial centers, which form ecological ill-being, is aggravated year by year. The aim of this article is to determine the degree of genome destabilization in deer—recognized as a source of anthropogenic pollution of the environment—living at different distances from the city of Norilsk. Using methods for determining the frequency of micronuclei and the state of interphase nucleous organizers, a higher destabilization of the deer genome has been found in areas up to 150 km compared to the area of more than 450 km away from Norilsk.
