Question
te 11. DNA fingerprinting is a method used to identify individuals by locating unique base sequences in their DNA molecules. Before researchers refined the method, attorneys often relied on ABO blood-typing to settle disputes over paternity. Suppose that you, as a geneticist, are asked to testify during a paternity case in which the mother has type A blood, the child has type bleod, and the alleged father has type B blood. How would you respond to the following statements? a. Attorney for the alleged father: "The mother's blood is type A, so the child's type O blood must have come from the father. My client has type B blood; he could not be the father." b. Mother's attorney: "Further tests show that the man is heterozygous. Therefore, he must be the father."Explanation / Answer
Answer:
According to Mother's attorney, if the father is heterozygous for type B blood he must be the father of the child as follows.
Mother (IAi) x Father (IBi)---Parents
So the type O child is possible.
IB i IA IAIB (AB) IAi(A) i IBi (B) ii (O)Related Questions
