Which of the following is an example of discontinuous variation?
Answer Details
Blood group is an example of discontinuous variation. Discontinuous variation is a variation in which individuals of a population can be divided into distinct groups based on certain traits. Blood groups are determined by the presence or absence of specific antigens on the surface of red blood cells, and there are only a limited number of blood types that exist in a population. Therefore, individuals can be grouped into distinct categories based on their blood group, making it an example of discontinuous variation. In contrast, traits such as height and foot length show continuous variation, as there is a range of values that individuals can exhibit within a population.
