NEET (UG) 2024 — Question 190

As per $A B O$ blood grouping system, the blood group of father is $\mathrm{B}^{+}$ , mother is $\mathrm{A}^{+}$ and child is $\mathrm{O}^{+}$ . Their respective genotype can be

A. $\mid \mathrm{Bi}_{\mathrm{i}} / \mathrm{A}_{\mathrm{i}} / \mathrm{ii}$

B. $\quad|B|^{B /} /\left.\left.\right|^{A}\right|^{A} / i i$

C. $A^{\mathrm{A}} \mathrm{B}^{\mathrm{B}} / \mathrm{I}^{\mathrm{A}} /\left.\right|^{\mathrm{B}} \mathrm{B}$

D. $\mid \mathrm{A}_{\mathrm{i}} / \mathrm{B}_{\mathrm{i}} / / \mathrm{A}_{\mathrm{i}}$

E. $\quad i i^{B} / i^{A} /\left.\left.\right|^{A}\right|^{B}$

Choose the most appropriate answer from the options given below :

Option A:
A only
Correct
Option B:
B only
Option C:
C & B only
Option D:
D & E only

Answer: A

Step-by-step solution

Genotype of father with blood group $\mathrm{B}^{+}=\mid \mathrm{Bi}_{i} / \mathrm{I}^{\mathrm{B}}$

Genotype of mother with blood group $\mathrm{A}^{+}=\mid \mathrm{A}_{\mathrm{i}} / \mathrm{i}^{\mathrm{A}}$

Genotype of child with blood group $\mathrm{O}^{+}=\mathrm{ii}$

Hence only ' A ' is correct.
