O blood
There are actually millions of blood types, but the 8 main types of human blood are as follows:O positiveO negativeA positiveA negativeB positiveB negativeAB positiveAB negativeOf these, the most common blood type is O positive. The most uncommon blood type is AB negative.
The most common blood type is O+, which is 40% of humans blood type.
Having a positive blood group can be beneficial because it is the most common blood type, making it easier to find compatible blood donors in case of a transfusion. Additionally, individuals with a positive blood group may have a reduced risk of certain health conditions compared to those with a negative blood group.
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+.

Humans whom are B+ fall into the category of having the third most common blood type, and that is on a global level. Coming in at first with being the most popular (i.e. meaning that this is the group where the majority of humans will be categorized in) will be those with a blood type of O+ as they will be universal donors. Coming in at number two is A+, then B+, and from that point it decreases more and more with AB+, O-, A-, B-, AB- (which is the rarest blood type to have).
Blood type O is known as the universal blood group as it occurs most often in humans.
