EVALUATION OF GENETIC STRUCTURE OF EUROPEAN BISON ( <i>BISON BONASUS</i> L.) BY A SINGLE NUCLEOTIDE POLYMORPHISM GENES <i>DRB3</i> AND <i>DQB</i> OF MAJOR HISTOCOMPATIBILITY COMPLEX (МНС)
Differences were shown in the genetic structure of the Belarusian and Polish populations of european bison for SNP-substitutions of genes DRB3 and DQB of the major histocompatibility complex (MHC), involved in the immune response implementation. Unique and rare alleles, which are valuable for the population and will contribute to an increase in genetic diversity and the species viability, were identified.
