Explanation:
Detailed explanation-1: -So, the probability of having a child of the B blood group is 50%. Q.
Detailed explanation-2: -When one of the inherited alleles is A and the other is B, the genotype is heterozygous and the blood type is AB. AB blood type is an example of co-dominance since both traits are expressed equally.
Detailed explanation-3: -Based on Punnett Square, there is a 25% probability that the child will have an O-blood type.
Detailed explanation-4: -Two parents with A blood type can produce a child with either A or O blood types. Two parents with B blood type can produce a child with either B or O blood type.
