Michelle, blood type AB, claims that Mark, blood type O is the father of her child, blood
type A. Is Mark the father of her child?
A:
Yes, Mark is the father of her child.
B:
No, Mark is excluded based on bloodtype.
C:
Mark could possibly be the father of her child.

Respuesta :

Answer: C

Explanation:

Mark could be the father of the child since he inherited two O alleles from each parent. Since Michelle inherited an A, and B allele. It is possible the child inherited a O allele from Mark, and a A allele from Michelle resulting in the child having an A Blood type. BUT the only way to truly know for sure is through DNA testing.
