(B) The gene $I$ controls the $ABO$ blood grouping in humans. This gene has three alleles: $I^A$,$I^B$,and $i$. The alleles $I^A$ and $I^B$ produce specific sugar polymers (polysaccharides) on the surface of the plasma membrane of red blood cells,which act as antigens. The allele $i$ does not produce any sugar. Therefore,these antigens are composed of polysaccharides.
