INBREED AND INTERBREED DIFFERENTIATION OF CATTLE
In modern selection and breeding work, the study and use of immunogenetic indicators of animals is of great importance, since it gives an idea of the genetic structure of the population and subsequently allows you to conduct purposefully breeding work with them. The aim was to compare the genetic polymorphism of blood groups in cattle of different breeds, to assess their genetic structure, to identify genetic distances between breeds, as well as to compare the blood groups of Kalmyk cattle in the Republic of Kalmykia and the Astrakhan region.
