how did the discovery of the rhesus factor affect society?\nmore patients died from having a transfusion with the wrong rhesus factor.\nnew treatments during pregnancy could prevent harm to the developing child.\nless donated blood could be used in the treatment of patients.\nthe number of blood types was reduced by half.
Answer
Brief Explanations:
The discovery of the rhesus factor led to better - understanding of blood compatibility, especially in pregnancy. It enabled new treatments to prevent harm to the fetus in cases where the mother and fetus have different rhesus factor statuses. Incorrect transfusion due to rhesus factor would cause more deaths before its discovery, not after. Also, more blood can be used with proper rhesus - factor matching, and the number of blood types did not reduce by half.
Answer:
New treatments during pregnancy could prevent harm to the developing child.
