Answer:
(a) IaIa and IbIo
The above given option is correct. If we consider the genotypes of the pregnant woman and her husband as IaIa and IbIo , and cross them, the square will be as follows:
Ib
Io
Ia
IaIb (AB)
IaIo (A)
Ia
IaIb (AB)
IaIo (A)
The square explains that the ration of occurrence of blood group A and blood group AB is 1:1. This means the woman has equal chance of having child with blood group A or AB.
