I believe the answer is: owing to a founder effect, many Native American populations have high frequencies of the O blood type.

While any other blood type can only donated to others with similar blood type (blood type A could only be donated to blood type A, blood type B could only be donated to blood type B, etc), that is not the case with blood type O.

The O blood type is what people referred to as a universal donor, which mean it can be donated to any other blood types, which make them perfect for blood banks.
