Which infant would be more likely to have 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 whose mother 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 whose mother is Rh positive
ANS: A
If the mother is Rh negative and the father is Rh positive and homozygous for the Rh factor, all the children will be Rh positive. Only Rh-positive children of an Rh-negative mother are at risk for Rh incompatibility. If the mother is Rh negative and the father is Rh positive and heterozygous for the factor, there is a 50% chance that each infant born of the union will be Rh positive and a 50% chance that each will be born Rh negative.
