The four blood types are A, B, AB and OThe probability that their offspring would have A blood type is 100%. Since one of the parents is homozygous for type A blood while the other is type O

The probability that their offspring would have B blood type is zero (0) since neither of the parents have B antigene

The probability that their offspring would have AB blood type is zero (0) since neither of the parents have B antigene.

The probability that their offspring would have B blood type is zero (0) since only one of the parents have O antigene. The other parent is homozygous for type A, which means the antigens are AA.

Answer:

The offspring would have type A blood group.

The genotype of mother would be [tex]I^{A}I^{A}[/tex] (homozygous type A blood group).

Thus, she will produce only one type of gamete that is, [tex]I^{A}[/tex].

Similarly, the genotype of a the father would be ii (type O blood group).

He will also produce only one type of gamete that is, i.

The cross would produce offspring with genotype [tex]I^{A}i[/tex].

Thus, the offspring would have only type A blood group.

Hence, the probability of having blood group A would be 100% and probability of having other blood group (B, AB or O) would be zero %.
