What Blood types in babies?

Babies inherit their blood type from their parents, determined by the ABO and Rh blood group systems. The ABO system includes four main blood types: A, B, AB, and O, which are influenced by the presence of specific antigens. The Rh factor can be either positive or negative, depending on whether the Rh antigen is present. Therefore, a baby's blood type can vary widely based on the combinations of their parents' blood types.
