A woman who is Rh^- becomes pregnant by a man who is Rh⁺. Which statement is true?

Question

Quizplus · Accepted Answer

Based on the parents' Rh phenotypes, there is a chance the baby can inherit the Rh⁺ genotype from the father. The Rh antigen is inherited in a codominant manner, meaning both the mother and father's antigens can express themselves in the baby's phenotype. Therefore, there is a chance the baby can be Rh positive, and if the baby is Rh positive and the mother's immune system is sensitized, there is a risk for hemolytic disease of the newborn. Option A is incorrect because the baby can inherit the Rh⁺ genotype. Option B is incorrect because there is still a chance of hemolytic disease of the newborn. Option C is incorrect because the mother does have Rh markers. Option D is incorrect because not all Rh-positive individuals produce Rh antibodies.
