Answer to Question 1

ANS: C
Structural defects are present in the qualitative hemoglobinopathies.

Answer to Question 2

ANS: A
This occurs in infants whose mothers make an IgG anti-A (in this case) or anti-B at a low level. The disease is usually mild because most ABO antibodies are IgM and do not cross the placenta because of their large size.
