Question

A man with blood group 'A' marries a woman with blood group 'B'. Their child has a blood group 'O'. What are genotypes of the parents?

• A. $I^A{I}^A,I^B{I}^B$
• B. $I^{A}i,I^{B}i$
• C. $I^{A}i,I^B{I}^B$
• D. $I^A{I}^B,I^A{I}^B$.

Answer 1

The correct option is B $I^{A}i,I^{B}i$

A man with blood group A(I^AI^O) marries a woman with blood group B(I^BI^O). The children has a blood group O.

So, the correct option is ‘I^AI^O, I^BI^O’.
