The four main groups are... Group O+ (the commonest), group A+, group B+ and group AB+
The four basic blood types are A, B, AB, and O.
All four of the basic blood types can be either be positive or negative, they are A,B,AB, and O. Blood types are used to used define each person blood, they help to make blood transfusions more successful by matching up the blood types.
The four main blood types are A, B, AB, and O. Each blood type is determined by the presence or absence of specific antigens on the surface of red blood cells. Additionally, blood types are classified based on the presence of the Rh factor, resulting in positive or negative blood types.
A, b, ab, o

The 1898 discovery of the four blood types (A, B, AB, O) did not directly lead to the discovery of the Rh factor, which was identified later in 1940. The discovery of the four blood types laid the foundation for understanding blood transfusions and paved the way for safer and more successful blood transfusions in medicine.
There is four types of blood in humans A B AB and O.But in each of them types there are a possible of at least 20 genetically blood vgroups known today.
One non harmful antigen type is blood types. These carry antigens that are not typically harmful to humans. The common blood types are: A, B, AB and O.
The four blood types are A, B, AB, and O. Blood type O is the universal donor because it does not have A or B antigens on its red blood cells. Blood type AB is the universal recipient as it does not have antibodies against A or B antigens.
oxygen blood cells and non-oxygen blood cells
Yes, there are only four official types of blood from which there are 30 substances and over 600 different blood-group antigens have been found across the varies ethnic groups.
The most common blood type is O. This is referred to as the universal donor. The other three types are A,B and AB blood types. The O type is compatiable with the other three types of blood.
