B-Negative (B-) blood comes from individuals who possess the B antigen on the surface of their red blood cells but do not have the Rh factor, which is a protein that can be present (+) or absent (-). Blood types are determined by genetic inheritance, and B-Neg is relatively rare, making up a small percentage of the population. Blood donations from B-Neg individuals are crucial for transfusions, especially for patients with compatible blood types.
