A
OO
B
type O
C
AA
D
type A
Explanation: 

Detailed explanation-1: -The A and B alleles are codominant. Therefore, if an A is inherited from one parent and a B from the other, the phenotype will be AB. Agglutination tests will show that these individuals have the characteristics of both type A and type B blood.

Detailed explanation-2: -Answer and Explanation: If a AB blood type woman and a O blood type man have a child, then their children’s probable blood type will be either A or B blood type.

Detailed explanation-3: -Usually, an AB parent and an A parent can only have children who are Type A or Type B. One exception is in certain Asian groups. Some of these folks have a rare version of the ABO blood type gene called cis-AB. People with this gene version have an AB blood type but can easily have an O child.
