A woman who has blood type A positive has a daughter who is type O positive and a son who is type B negative. Rh positive is a trait that shows simple dominance over Rh negative and is designated by the alleles R and r, respectively. A third gene for the MN blood group has codominant alleles M and N.

Hello. This question is incomplete. The full question is:

"A woman who has blood type A positive has a daughter who is type O positive and a son who is type B negative. Rh positive is a trait that shows simple dominance over Rh negative and is designated by the alleles R and r, respectively.

Which of the following is a possible genotype for the mother?  

a. IAIB   b. IAIA  c. ii  d. IAi  e. IBIB"

d. IAi

Explanation:

As we know, there are four types of blood, which are: A, B, AB and O.

There are three genes responsible for determining the blood type in humans, these genes are called IA, IB and i.

The genes IA and IB are dominant in relation to gene i, but they do not present dominance among themselves. The "IA" gene refers to type A blood, the "IB" gene refers to type B blood, while the "i" gene refers to type O blood. In addition, bloods can be negative or positive in relation to whether or not they have the Rh suit.

Based on this, we can say that in relation to the question above, the only option that can represent the genotype of a woman who has positive type A blood is IAi.
