There are four main blood groups A, B, AB, O. Which are in the ABO blood grouping system. This blood typing system was discovered in 1901. The most common blood groups in this grouping system are A and O.
There is a Rh factor blood grouping system. Rh stands for rhesus. People have a so called Rh factor on the red blood cell's surface. This is also an antigen. People that have Rh antibodies naturally in the blood plasma are called Rh+. Those who haven't are called Rh-. A person with Rh- blood does not have Rh antibodies naturally in the blood. But a person with Rh- blood can develop Rh antibodies in the blood plasma if they receive blood from a person with Rh+ blood, whose Rh antigens can trigger the production of the Rh antibodies. A person with Rh+ blood can receive blood from a person with Rh- blood without any problems.
so you can belong to any of these blood types:
A Rh+
A Rh-
B Rh+
B Rh-
AB Rh+
AB Rh-
O Rh+
O Rh-
The rare Blood type Duffy-negative Blood, occurs much more frequently in people of African ancestry.
