Molly has blood type A and her daughter has blood type B. Why can't Molly donate blood to her daughter? Blood types A and B will coagulate during a transfusion. Mothers cannot donate blood to their daughters. Blood type B contains anti-A antibodies, which will agglutinate with type A blood. Blood transfusions cannot be performed among relatives. Only fathers can donate blood to their daughters.

What is the cause of the physiologic jaundice seen in some newborns? The low oxygen content of blood causes the skin to have a yellowish hue. The lack of iron in the newborn's diet limits the production of RBCs. The bone marrow is unable to produce new RBCs. Liver is too immature to handle the breakdown products of hemoglobin if fetal RBCs are rapidly destroyed.
