In the ABO series of human blood types, people have only one kind of blood type, either A, B, AB, or O. This illustrates what kind of variation?

A. Continuous B. Contingent C. Discontinuous D. Genetic

Answer:

C. Discontinuous

Explanation:

ABO blood type in humans is regulated by three alleles of a gene. various combinations of these three alleles give a total of four types of phenotypes that can be present in a population. When a person has two copies of I^A alleles, its blood type will be type "A". It is an example of discontinuous genetic variation since the phenotypes are present in distinct categories and do not exhibit a range of continuous variations as the skin color does.
