In this scenario, the man has blood type AB, and the woman has blood type B. Given the ABO blood type inheritance patterns, the possible blood types for their child are:
c. Blood types A, B, and AB
When a person with blood type AB (genotype: IAIB) has offspring with someone who has blood type B (genotype: IBIB or IBi), the potential combinations of their alleles can result in children with blood types A (genotype: IAi), B (genotype: IBIB or IBi), or AB (genotype: IAIB).
Therefore, their child could potentially inherit the A allele from the father (IA) and the B allele from the mother (IB), resulting in blood type AB, or the A or B allele from the mother, resulting in blood types A or B, respectively.
