A mother with type O blood gives birth to a baby.
The father has type AB blood.
The possible blood types that the baby could have would either be (a) or (b)
Red blood cells carry antigens on their surfaces coded for by alleles of the gene designated by the letter I. IA is dominant to i and produces antigen A on the surface of red blood cells. The IB allele is also dominant to the i allele and produces antigen B on the surface of red blood cells. The i allele does not produce surface antigens.
Use this information to label the possible genotypes of each blood type.

Match the following
Type A

Type B
Has B antigens.
BB or BO
Type AB
Has both A and B antigens
Type O
No antigens are on the blood cell
