Principles of Inheritance and Variation

As per the ABO blood grouping system, the blood group of the father is B+, the mother is A+ and the child is O+. Their respective genotypes can be:

A. ${\mathrm{I}}^{\mathrm{B}}i/{\mathrm{I}}^{\mathrm{A}}i/ii$ · B. ${\mathrm{I}}^{\mathrm{B}}{\mathrm{I}}^{\mathrm{B}}/{\mathrm{I}}^{\mathrm{A}}{\mathrm{I}}^{\mathrm{A}}/ii$ · C. ${\mathrm{I}}^{\mathrm{A}}{\mathrm{I}}^{\mathrm{B}}/i{\mathrm{I}}^{\mathrm{A}}/{\mathrm{I}}^{\mathrm{B}}\mathrm{i}$ · D. ${\mathrm{I}}^{\mathrm{A}}i/{\mathrm{I}}^{\mathrm{B}}i/{\mathrm{I}}^{\mathrm{A}}\mathrm{i}$ · E. $\mathrm{i}{\mathrm{I}}^{\mathrm{B}}/i{\mathrm{I}}^{\mathrm{A}}/{\mathrm{I}}^{\mathrm{A}}{\mathrm{I}}^{\mathrm{B}}$
