  • O positive
  • O negative
  • A positive
  • A negative
  • B positive

There are two parts to a blood group in humans;

A, B, AB, or O (niether A or B)

then you are either rhesus positive or rhesus negative, so there are 8 main combinations.

The most common is someone who is O group and then rhesus positive. This is about 37% of the population.
