Question

An individual who has the blood groups IA and IB has the phenotype of AB blood. What is the phenotype of the offspring of two parents with AB blood? 4AB O1A: 2AB:1 B O 20:2 AB O2 A and 2B

Answer 1

When two parents with AB blood type have children, the possible phenotypes of their offspring can be 4AB, 2A, and 1B.

Step-by-step explanation:

When two individuals with AB blood types have children, the children can have the phenotypes A, B, or AB. This is because the ABO blood groups in humans are controlled by the IA, IB, and i alleles, with IA encoding the A blood group antigen, IB encoding the B blood group antigen, and i encoding the O blood group antigen. Both the IA and IB alleles are dominant to the i allele. So, if two parents with AB blood type (1A1B) have offspring, the possible phenotypes of their children can be 4AB, 2A, and 1B.
