Detailed explanation-1: -BLOOD TYPE & RH FACTOR The ABO group and Rh type classify a group of genetically inherited antigens found in the outer membrane of each red blood cell. The ABO group consists of four possibilities: A, B, AB, and O. The Rh type is either positive or negative.

Detailed explanation-2: -In the United States, AB-negative is the rarest blood type, white O-positive is the most common. Your blood type is based on genetics and whether it contains certain antigens. While AB/Rh-negative may be the rarest blood type in the United States, this is not the case worldwide.

Detailed explanation-3: -The main difference between ABO blood group and RH blood group is that ABO blood group is determined by the presence or absence of A and B antigens on the surface of the red blood cell whereas RH blood group is determined by the presence or absence of D antigen on the surface of the red blood cell.
