If a child is of blood group-O and his father is of blood group-B, the genotype of father will be

A)           \[{{I}^{O}}{{I}^{O}}\]                           

B)                  \[{{I}^{A}}{{I}^{B}}\]                                           

C)                  \[{{I}^{O}}{{I}^{B}}\]

D)                  \[{{I}^{O}}{{I}^{A}}\]

Correct Answer: C

Solution :

Genotype of a person with blood group-B may be \[{{I}^{B}}{{I}^{B}}\] or \[{{I}^{O}}{{I}^{B}}\]. Person with genotype \[{{I}^{B}}{{I}^{B}}\] cannot produce offsprings with blood group-0 but if the genotype of person is \[{{I}^{O}}{{I}^{B}}\] it produces offsprings of blood group-O.
