Question

BIO GRADE 8:
What happens if a person with Rhesus negative blood receives Rhesus positive blood?

Answer 1

Answer:

This is because an Rh-positive blood transfusion can cause a person with Rh negative blood to make antibodies against the Rh factor, causing a transfusion reaction (discussed below). If an Rh-negative woman makes antibodies like this, it can seriously harm any Rh-positive babies she may have in the future.
