Question

A family charged the hospital with baby swapping, claiming that the baby they brought home was not their biological daughter. The father and the baby had type B blood, the mother type O. In terms of blood type, could the baby have belonged to this couple

Answer 1

First, recall that for the mother to have O, she will have both alleles to be O. And remember that O is recessive to A and B. For the father to be B, he can have BB or BO. From this, what are the possible combinations for their offspring?

Answer 2

a) Yes, this couple could have a child with either iBiB or IBi, both type B phenotype
b)no, type O mother could not have a type B child
c) yes the baby could have Ibi genotype
d) yes, iB is dominant to i, so a B father and an O mother would always have kids with type B blood

Answer 3

this are the choices

Answer 4

Answer 5

Please read what I posted and I'll follow you through

Answer 6

So father is IbIb and mother is ii ?

Answer 7

I think it'd be c?

Answer 8

The father can have BB or BO. Mom is OO. So baby can have BO or OO, making it either B type or O type.

From this, I would say C is correct.
