Question

Q Why does Erythroblastosis Details occurs with
a second pregnany ?​

Answer 1

Answer:

With the second pregnancy, the little bit of fetal blood that enters the maternal system is sufficient to produce an immune response (since the Mom's immune system is now more sensitive to that protein), and antibodies to the D protein begin to attack the fetal RBC's. This results in erythroblastosis fetalis.
