Variation within organisms refers to how different they are from another. In biology, variation can either be a continuous one or discontinuous.
A continuous variation is a type of variation in which there is a wide range of values from one phenotype/extreme to the other. In other words, there are a lot of values in between the extremes. For example, the human height can range from different degree of shortness to a different degree of tallness. Hence, human height is an example of a trait that exhibit continuous variation.
Therefore, a variation which exhibits a wide range from one extreme to the other is CONTINUOS VARIATION.
