QuestionChoice
Rhesus-negative mothers have no anti-rhesus antibodies. However, if exposed to the rhesus antigens of a rhesus-positive baby they will develop these antibodies. Therefore, in future pregnancies, there is a risk that these maternal antibodies can attack the rhesus antigens on the red blood cells of a future rhesus-positive fetus - causing haemolysis. To prevent this, anti-D immunoglobulin.

d
Rhesus-positive woman with a rhesus-negative baby who underwent an amniocentesis
QuestionChoice
As the fetus has no rhesus antigens in its blood even if the mother's blood is exposed to fetal blood, there will be no antibodies formed.
