Question

Quizplus · Accepted Answer

Hemolytic disease of the newborn is caused by the mother's Rh- blood forming antibodies against Rh+ blood, which can happen if the father is Rh+ and the child inherits his Rh+ blood type. However, if the father is Rh-, there is no chance the child can inherit Rh+ blood, so hemolytic disease of the newborn will not occur. The child's ABO blood type (O positive in choice D) is not relevant to the situation, as hemolytic disease of the newborn is specifically related to the Rh factor.
