Blood groups are a classification system for human beings based on the presence or absence of specific antigens on the surface of red blood cells. These antigens are proteins found in the red blood cells of people with different blood types. Blood type is determined by the alleles of three genes: A, B, and O.
There are four main blood groups:
Group A: Individuals with blood type A have antigen A on their red blood cells.
Group B: Individuals with blood type B have antigen B on their red blood cells.
Group AB: Individuals with blood type AB have neither antigen A nor B on their red blood cells.
Group O: Individuals with blood type O have neither antigen A nor B on their red blood cells.
Blood group is inherited from parents. A person receives one gene from their mother and one gene from their father. The genes for blood type are located on chromosomes 1 and 2.
Blood type is important because it is used in blood transfusions to ensure that people receive blood compatible with their own. This means that blood transfusions are safe and can help people who have lost blood due to injury or illness.
Blood type is also used in organ transplants. Surgeons use blood type compatibility to ensure that organs are matched between donor and recipient. This helps to prevent organ rejection and ensures that patients receive organs that are compatible with their own bodies
