In brief: Blood type
"blood group" and "blood type" are the same thing.
Blood types are as follows: a, b, o, and ab. There is also the rh factor, which is + or -. Blood types are inherited traits. Worldwide, o+ is the most common type, and ab- is the rarest type.

In brief: The term blood
Group is used in the same way as blood type, which is determined by surface molecules.
So the groups are o, a, b, and ab.
