Alloantibodies detecting antigenic determinats called BgC1 and AmiF1 were obtained in cattle.The analysis of determinants' inheritance was done on 1754 offsprings using 72 sires and 1740 dams.The molecule-carriers of both traits were characterized using serological and physico-chemical methods.It was found that 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.
