What is the frequency of the D antigen in the population?

Explanation:
The D antigen is the defining feature of Rh positivity, and it is expressed by the vast majority of people. The standard estimate across populations is about eighty-five percent, so the frequency of the D antigen is roughly 85%. That also means around 15% are D negative. The other values would imply notably different distributions than what is typically observed in Immunohematology data.
