In a hospital, three babes were born simultaneously during a thunderstorm. The lights went off for a few minutes. During that time, the babies were mixed. The hospital wants to be sure
that it is giving the right baby to the right parents by attempting to match the blood types.
Can you help?
Helpful information:
- The four human blood types are A, B, AB, and o
- Type A dominates O, so those have type A have either AA or AO.
- Type B dominates O, so those with type B have either BB or BO.
- Type AB, neither gene dominates; one gene is A, one is B.
- Type O is recessive to A and B, so it must be OO.

Can you match the correct baby with the correct parents? When determining the correct
pairing, support your claim with the following:
What is the genotype of the baby?
What are the possible parent genotypes needed to have a baby with the genotype you
identify?
-Why would the other babies NOT be able to belong to the parent you identified?
