Answer:
Yes the hospital made a mistake.
Explanation:
The hospital made a mistake because parents with blood group A and AB cannot produce a child with blood group O.
The blood type of a baby is determined solely by the blood type of both parents. One of two alleles is given out by each biological parent to form the blood group of the child.
A mother who have blood group B and a father who have blood group AB will produce a child with either blood group A,B or AB.
Answer:
Yes, there was a mistake
Explanation:
The mother is of type B blood whose genotype can be BB or BO
The father is of type AB blood whose genotype is AB
The baby is of type O blood whose genotype is OO
Thus, if the mother is of BB and the father AB, the can only produce children of AB and B bloodtype.
If the mother is of BO and the father AB, the can only produce children of AB, A and B bloodtype. There will not be able to produce a child of O bloodtype in an of the cases above.
