The mother's body will produce antibodies to destroy fetal RBCs.
Why can a person with Rh-negative blood receive Rh-positive blood without issues?
Rh-negative blood lacks the Rh factor present in Rh-positive blood.
In the context of blood types, what does it mean for a trait to be autosomal recessive?

For a severely anemic fetus
What fetal assessment test may be used to detect fetal anemia resulting from Rh incompatibility?
