Which of the following is an example of discontinuous variation?
Answer Details
Blood groups of patients is an example of discontinuous variation. Discontinuous variation refers to traits that can only be expressed in certain discrete categories, with no intermediate forms between categories. Blood groups are a good example of this because they can only fall into certain categories (A, B, AB, or O) and there are no intermediate forms. Height, complexion, and weight can all vary continuously and can fall anywhere along a spectrum.
