#Section 2: General Biology

  1. The fetus in Case 3 would provoke an immune response in the mother that would carry over after the birth.

  2. The newborn in Case 3 would soon be able to make antibodies to the B antigen of the mother.

  3. Newborn children, until about age 2, do not make appreciable antibodies, except against Rh+ antigen. 

  4. Passive immunity would have worn off for the third newborn, but not for the other two.
