Variation which exhibits a wide range from one extreme to the other with very little difference between the intermediates is described as

The variation that exhibits a wide range from one extreme to the other with very little difference between the intermediates is called continuous variation. This type of variation can be seen in traits that are controlled by multiple genes and are influenced by both genetic and environmental factors. For example, human height is a trait that shows continuous variation, where individuals can vary in height from very short to very tall, with a wide range of intermediate heights in between. This type of variation can be represented by a bell-shaped curve, where most individuals fall in the middle of the range and fewer individuals are found at the extremes. In contrast, discontinuous variation refers to traits that have distinct, non-overlapping categories, such as blood type or eye color, and phenotypic and genotypic variations are related to the expression of traits, but they do not describe the range of variation exhibited.
