Here's a question i thought was interesting, let's see if you can get it.
A couple requests blood typing of their 2yr old child (father AB, Rh -ve; mother B, Rh -ve). Results of the hemagglutination assays of the child's blood are as follows:
+ = Hemagglutination, - = No Hemagglutiation
Saline + Child's RBC -
Anti A + Childr's RBC -
Anti B + Childr's RBC +
Anti D + Childr's RBC -
Child's serum + Type A RBC +
Child's serum + Type B RBC -
Child's serum + Type D RBC -
Which of the following conclusions concerning the child's parentage is valid?
a. The child is the natural offspring of this couple
b. The mother is the biological mother, but the father is not
c. The father is the biological father, but the mother is not
d. Neither one is the biological parent
what do you think the answer is, and why?
