a.
To determine: The genotypes of the parent when all their children have Rh+ blood group.
Introduction: There are two types of Rh blood groups: Rh+ (have Rh antigen) and Rh- (do not have Rh antigen). Rh factor is a point of concern when the mother has Rh- and fetus has Rh+ blood group. This condition can cause hemolytic disease of newborn baby (HDN).
b.
To determine: Whether the parents in the given case should be concerned about the risk of the occurrence of hemolytic disease to the newborn.
Introduction: There are two types of Rh blood groups: Rh+ (have Rh antigen) and Rh- (do not have Rh antigen). Rh factor is a point of concern when the mother has Rh- and fetus has Rh+ blood group. This condition can cause hemolytic disease of newborn baby (HDN).
