Zoology - Principles of Inheritance and Variation Question with Solution | TestHub

Father has AB blood group, so his genotype is${\mathrm{I}}^{\mathrm{A}}{\mathrm{I}}^{\mathrm{B}}$. Mother has A blood group, so her genotype could be${\mathrm{I}}^{\mathrm{A}}{\mathrm{I}}^{\mathrm{A}}$or${\mathrm{I}}^{\mathrm{A}}{\mathrm{I}}^{\mathrm{O}}$. For getting all the possibilities we have to assume that mother is heterozygous. Father will produce two types of gametes, one with${\mathrm{I}}^{\mathrm{A}}$while the other has${\mathrm{I}}^{\mathrm{B}}$. The mother will also produce two types of gametes, one with${\mathrm{I}}^{\mathrm{A}}$while the other has${\mathrm{I}}^{\mathrm{O}}$.
