between the descendants of different bulls in the period from 2003 till 2013. According to AEB-locus at the descendants of all bulls from 25 studied antigens common were only 6 – B2, G2, O2, Y2, E′2 and Q′. The total meeting of frequency of the basic alleles varied from 0,2250 (the descendants of bull Chiparush 79) till 0,4071 (the descendants of bull Dickey 788). The lowest coefficient of homozygote turned out to be at the descendants Abiturient 861 and Svet 732 – 5,7%. The greatest genetical resemblance is revealed between the descendants of bulls Academic 767 and Senior 7415 (r=0,8709). It is observed the tendency of increasing of coefficient of homozygote (descendants 2009-2013 date of birth) - 18%, that brought to the shortening of numbers of effective working alleles from 17,3 (the descendants of bull Abiturient) till 5,4 (descendants of bull Meteor) and to shortening till 86,4% the indicator of the degree of the possible genetical changeability.
