Alloantibodies detecting antigenic determinants called BgC1 and AmiF1 were obtained in cattle. The analysis of determinants' inheritance was done on 1754 offsprings after 72 sires and 1740 dams. The molecule-carriers of both traits were characterized using serological and physico-chemical methods. It was found that the identified determinants are markers of beta-globulin and alpha-microglobulin proteins, and of autosomal, dominant genes BgC1 and AmiF1 from independent loci, which control them.
