What is the least common blood type in humans?
When discussing blood types, the two groupings most commonly used are the ABO (A, B, AB, O) and Rh (+, -) systems. The least common blood type in humans is Bombay (EXTREMELY rare), which is a type O with missing H antigen. Otherwise, of the "normal" ABO and Rh typings, the least common group is AB-. ABO from most to least frequent: O, A, B, AB. The relative frequencies of these groups varies depending on race. The relative frequences of Rh+ and Rh- individuals also varies with race. About 85% of "whites" are Rh+, while 99.8% of American Indians are Rh+.

What does Rh positive blood mean and how is it differerent to RH negative blood?
Your blood type is determined (genetically) by the presence or absence of specific surface antigens on the membrane of the RBC. The most important RBC surface antigens are A, B and Rh.Blood can be either Rh positive(Rh+) or Rh negative (Rh-) depending on the presence (Rh+) or absence of the Rh antigen (Rh-) on the surface of the cell.Unlike the ABO system, type Rh- blood does not normally carry anti-Rh antibodies, unless the individual has been sensitized by previous exposure (usually pregnancy).The most common blood type is O+.
Are B and Rh one blood type or two different blood types?
B and Rh are two different blood type systems. The B blood type refers to the presence of the B antigen on red blood cells, while the Rh factor (Rh positive or Rh negative) refers to the presence or absence of the Rh antigen. This means someone could have blood type B+ or B-, indicating their blood type in both systems.

What are Rh antigens?
They are a type of antigen that some people carry on their red blood cells. They are called "rhesus" because they were initially identified and studied on the red blood cells of rhesus monkeys, then were later also found in humans. If a person has Rh+ blood type they have this antigen, if a person has Rh- blood type they do not. They are important in blood transfusions in that a person with Rh+ blood type can receive either Rh+ or Rh- blood with no problems, but a person with Rh- blood type can only receive Rh- blood (Rh+ blood could kill him when antibodies from his immune system attack the rhesus antigen, causing massive blood clotting). They are important in pregnancy in that a woman with Rh- blood type has a much higher chance of miscarriage if her baby has Rh+ blood type. Note: there are roughly 30 different classes of blood type antigens, not just the familiar A, B, and Rh antigens. Most however are very rare.
