The object of this investigation was the genetic polymorphism of transferrins in Altaian and Mongolian yaks and in the aboriginal cattle of high-mountain regions of the Altai Territory. Both in the cattle and in yaks the usual 4-allele system of the transferin locus with a peculiar frequency and distribution of genotypes was found. A high frequency of occurrence of transferrin types D1 and D2 under the conditions of a severe pressure of natural selection suggests the existence of a correlation between the TF-genotypes and the adaptive capacities of the given cattle species.
