If the father's blood type is O and mother's blood type is A what type of blood will the baby have?

Answer:

The blood group can be 'O' or 'A'.

It is because of multiple alleles

The person with blood group O has only 1 possibility of IO IO

while the person with the blood group A can have 2 possibilities IAIA or IAIO

so if the probability is taken out there are only 2 types possible i.e. blood group A or O
