 Monіtoring of pig home karyotypic variability continues detect constitutive cytogenetic damage carriers, most of whom are reciprocal translocations. Analyzed the variability of different chromosomes in terms of their length, contents of genes and QTL and participation in cytogenetic damage. Analysis of Sus scrofa population karyotypic variability, which are reproduced in different radioecological conditions, indicates that the cytogenetic parameters of pigs somatic mutagenesis ranges are: the frequency of cells with micronuclei — from 1,3±0,3 to 7,13±0,82 ‰, binucleate — 0,72±0,27 to 5,2±0,3 ‰, mitotic index — from 1,5±0,53 to 10,4±0,4 ‰. The frequency of metaphases with aneuploidy — from 4,50±0,98 to 18,55±3,39 %, asynchronous splitting chromatid centromere regions — from 1,34±0,02 to 6,23±0,05 %, with polyploidy — from 0,3±0,21 to 1,73±0,63 %, with chromosomal aberrations — from 0 to 5,69±0,12 %. Under the influence of low-dose ionizing radiation, there is increased frequency of cells with micronuclei, aneuploidy metaphases, asynchronous cleavage of centromeric regions of chromosomes, dicentric and ring chromosomes.
