AB blood contains anti-A antibodies, which would react with A antigens in the recipient's blood.

AB blood contains B antigens, which would react with anti-B antibodies in the recipient's blood.

AB blood lacks both A and B antigens.

AB blood contains both anti-A and anti-B antibodies.

The gene (I) has three alleles.

A person will have only two of three alleles.

When ${{\rm{I}}^{\rm{A}}}\,\,{\rm{and}}\,\,{{\rm{I}}^{\rm{B}}}$ are present together, they express same type of sugar.

Allele ‘i’ does not produce any sugar.
