What are the possible blood groups likely to be inherited by children born to a group A mother and a group B father? Explain your reasoning.

Answer 1

The mother with blood group A has genotype I^AI^O. The father with blood group B has genotype I^BI^O. Hence ,the possible genotypes of the children will be I^AI^B, I^AI^O, I^BI^O and I^OI^O. Thus, the possible blood groups of the children will be AB, A, B and O.
