Was ist die seltenste Blutgruppe?<end_of_turn>
<start_of_turn>model
The rarest blood type is AB negative (AB-). It is found in a very small percentage of the world's population. Individuals with blood type AB negative have both the A and B antigens on the surface of their red blood cells, but do not have the Rh factor (Rh-negative). This combination makes the AB negative blood type rare and it is often sought after for medical treatments, because people with AB negative blood can receive blood from donors with AB negative, A negative, B negative, or O negative blood types. However, they can only donate blood to other people with AB negative blood type.<end_of_turn><eos>
