Is O blood common in Native Americans?

Where does the O negative blood type come from?
Higher rates of O negative blood type are found in people from Spain, Iceland, New Zealand, and Australia. There are several blood types including A+, A-, B+, B-, AB+, AB-, O+, and O-. The blood type of a person is determined by chromosome 9. A child born to parents who are both O will also be O.

Why blood group O is most common in a population?
O type is the most common despite being a recessive gene because it is more highly expressed in the gene pool, while type A and type B are dominant (and type AB is codominant) but are less common because they are less expressed in the gene pool.
What is the most rare blood type by ethnicity?
