Answer

Brief Explanations:

The rhesus (Rh) factor is an important blood - type antigen. Rh - negative individuals do not have the Rh antigen on their red blood cells. If they receive Rh - positive blood, their immune system may produce antibodies against the Rh antigen, leading to a transfusion reaction. So, an Rh - negative patient can receive only Rh - negative blood. Rh - positive patients can receive both Rh - positive and Rh - negative blood.

Answer:

A patient who is Rh− can receive only Rh− blood.
