8. The ABO blood groups in humans are expressed as the \( I^{A} \), \( I^{B} \), and \( i \) alleles. The \( I^{A} \) allele encodes the A blood group antigen, \( I^{B} \) encodes B , and \( i \) encodes O . Both A and B are dominant to O. If a heterozygous blood type A parent \( \left(I^{A}\right) \) and a heterozygous blood type B parent \( \left(I^{B} i\right) \) mate, one quarter of their offspring are expected to have the AB blood type ( \( \left.I^{A} I^{B}\right) \) in which both antigens are expressed equally. Therefore, ABO blood groups are an example of: 1. multiple alleles and incomplete dominance 2. codominance and incomplete dominance 9. incomplete dominance only 4. multiple alleles and codominance
