      4 major groups; A B O and AB

      O is what most people in uk are.
      AB is rare

      There is many other classifications that just these 4 but that is the major groups (landsteiner)

      4 major groups (O, AB, A and B) but many subtypes within these based on Rhesus classification so you can have O positive or O negative, AB positive or AB negative, and so on
