Show Answer
Answer:
Correct Answer: C
Solution:
- To determine the possible blood groups of the offspring, we need to consider the genotypes of the parents. Blood group A can have the genotype AA or AO, and blood group B can have the genotype BB or BO.
Let’s consider all possible combinations:
-
If the man is AA and the woman is BB:
- The offspring can only have the genotype AB, resulting in blood group AB.
-
If the man is AA and the woman is BO:
- The offspring can have the genotypes AB (blood group AB) or AO (blood group A).
-
If the man is AO and the woman is BB:
- The offspring can have the genotypes AB (blood group AB) or BO (blood group B).
-
If the man is AO and the woman is BO:
- The offspring can have the genotypes AB (blood group AB), AO (blood group A), BO (blood group B), or OO (blood group O).
Considering all these combinations, the possible blood groups of their offspring are A, B, AB, and O.
