In a marriage between male with blood group A and female with blood group B, the progeny had either blood group AB\mathrm{AB} or B\mathrm{B}. What could be the possible genotype of parents?In a marriage between male with blood group A and female with blood group B, the progeny had either blood group AB or B

Options

  1. A(I\mathrm{I}^{\mathrm{A}} \mathbf{i}(\text{Male}): I\mathrm{I}^{\mathrm{B}} I\mathrm{I}^{\mathrm{B}}) Female
  2. B(I\mathrm{I}^{\mathrm{A}} I\mathrm{I}^{\mathrm{A}} \text{ (Male) }: I\mathrm{I}^{\mathrm{B}} I\mathrm{I}^{\mathrm{B}}) Female
  3. C(I\mathrm{I}^{\mathrm{A}} I\mathrm{I}^{\mathrm{A}}(\text{Male}): I\mathrm{I}^{\mathrm{B}} \mathrm{i}) Female
  4. D(I\mathrm{I}^{\mathrm{A}} \mathrm{i}(\text{Male}): I\mathrm{I}^{\mathrm{B}} \mathbf{i}) Female

Correct answer

A. (I\mathrm{I}^{\mathrm{A}} \mathbf{i}(\text{Male}): I\mathrm{I}^{\mathrm{B}} I\mathrm{I}^{\mathrm{B}}) Female

Step-by-step solution

The possible genotype of parents having progeny with either blood group AB\mathrm{AB} or B\mathrm{B} is IAi\mathrm{I}^{\mathrm{A}} \mathrm{i} (male): IB\mathrm{I}^{\mathrm{B}}\mathrm{I}B^{\mathrm{B}} (female) In a marriage between male with blood group A and female with blood group B, the progeny had either blood group AB or B
