Final answer:
The possible genotypes of their offspring would be AO and BO, resulting in type A and type B blood respectively. The possible phenotypes of their offspring would be type A and type B. The woman can donate blood to her husband, as blood type O is the universal donor and the Rh factor is not a concern for plasma transfusion.
Step-by-step explanation:
The possible genotypes of their offspring in terms of ABO blood group can be determined using the Punnett square. The father is blood type AB, which means he has both the A and B alleles. The mother is blood type O, which means she has the ii genotype. The possible genotypes of their offspring would be AO and BO, resulting in type A and type B blood respectively.
The possible phenotypes of their offspring would be type A and type B, as explained in the previous section. This is because the presence of the A and B alleles in the father allows for the expression of both blood types, while the mother's O genotype doesn't have any antigen expression.
The woman, being blood type O and Rh-, can donate blood to her husband, who is blood type AB and Rh+. This is because blood type O is considered the universal donor for ABO blood groups, meaning it can be transfused to individuals with any blood type. The Rh factor, which is positive (+) in the husband, is not a concern in terms of blood compatibility for plasma transfusion.
On the other hand, the husband, who is blood type AB and Rh+, can donate blood to the wife who is blood type O and Rh-. Since type O is the universal recipient for ABO blood groups, it can receive blood from individuals with any blood type. Additionally, the Rh- factor in the wife's blood type is compatible with the Rh+ factor in the husband's blood type. Therefore, the husband can donate blood to his wife.
