توضیح
Discontinuous variation is when individuals fall into distinct categories or classes, and there are no values in between. Blood group is an example of discontinuous variation. In the ABO blood group system, there are only four possible blood groups: A, B, AB, or O. You can't have a blood group in between these four groups.
