2. Which infant is most likely to express Rh incompatibility?
a. Infant of an Rh-negative mother and a father who is Rh positive and homozygous for
the Rh factor
b. Infant who is Rh negative and a mother who is Rh negative
c. Infant of an Rh-negative mother and a father who is Rh positive and heterozygous for
the Rh factor
d. Infant who is Rh positive and a mother who is Rh positive - ANS: A
If the mother is Rh negative and the father is Rh positive and homozygous for the Rh
factor, then all the offspring of this union will be Rh positive. Only Rh-positive offspring
