Accepted Answer

A person's blood type is determined by the presence of specific glycoproteins on the cell membrane of the red blood cells. These glycoproteins are known as antigens and are classified into different blood groups, such as A, B, AB, and O. The presence or absence of these antigens determines a person's blood type. For example, people with blood type A have A antigens on their red blood cells, while people with blood type B have B antigens on their red blood cells.
