Question

A daughter has B blood group and her mother has O blood group. Her mother is allegedly accusing that Mr. X is her father. But court found that Mr. X is innocent directly on basis of his blood group. What blood group Mr. X would have

• A. A
• B. O
• C. B
• D. Either A or O

Answer 1

The correct option is D Either A or O

If both parents have blood group O (ii) then the daughter should also be having blood group O

If father has blood group $A\left(I^A{I}^A\right)$ , ii) and mother has O (ii) then daughter can have either $A\left(I^{A}i\right)$ or O (ii) blood group.

So, the father cannot be a person with the blood group O or A.
