GENETIC STRUCTURE OF DOWN GOATS OF MONGOLIA AND TUVA
Using microsatellite markers, the parameters of allelic and genetic diversity were obtained and the relationships between the aboriginal populations of Mongolian downy goats were established: gurvan egch, darkhat, burakh zavkhan, ulgiy uulan, altai uulan and two populations of Tuvan coarse wooled goats. The data obtained indicate the existence of a correlation of genetic relations between the considered populations of goats and their geographical distribution, as well as the influence of the influx of blood from improver breeds. Genetic differences between Mongolian and Tuvan goats were, on average, higher than between goat populations within the Mongolian and Tuvan groups of animals. At the same time, Mongolian downy goats were characterized by high intrapopulation diversity and a rather low level of genetic differences between populations
