Answer:
Craig is right and doesn't have to pay child support.
Explanation:
The complete question is
Susan, a mother with Type B blood, has a child with Type O blood. She claims that Craig, who has Type A blood, is the father. He claims that he cannot possibly be the father. Further blood tests ordered by the judge reveal that Craig is AA. The judge rules that:
a. Susan is right and Craig must pay child support
b. Craig is right and doesn't have to pay child support
c. Susan cannot be the real mother of the child; there must have been an error made at the hospital
d. it is impossible to reach a decision based on the limited data available
- The blood type of a child is determined by the blood type of the parents, and the rules are as given in the attached diagram.
- Based on these rules, it can be observed that a person with type O blood group must have the genotype OO and from this, it can be concluded that both the parents must carry an O allele.
- Since the blood typing has revealed that Craig is AA, he can't be the father of the child and hence, he doesn't have to pay child support.
