Could someone please check this definition and tell me if it's good or if it's too much (whatever)

Variation=the existence of differences between the individuals in a population. It can be described as continuous or discrete. Examples of discrete variation are gender and eye colour which often arises when the character is controlled by a small number of alleles. An Example of continuous variation is height. Continous variation often arises when a large number of independent factors influence the character. Only variations due to genetic constitutions can be inherited.

To check whether a definition is good or too much, we can break it down and analyze its components.

In this definition of variation, several aspects are covered:
1. The definition starts by stating that variation refers to the existence of differences between individuals in a population. This establishes the primary concept of variation as the presence of diversity within a group of organisms.
2. It then introduces the idea that variation can be described as either continuous or discrete. Discrete variation refers to traits that can be categorized into distinct categories, such as gender and eye color. Continuous variation, on the other hand, refers to traits that exist on a spectrum or scale, like height. This differentiation helps illustrate the different types of variations that can occur.
3. The definition provides examples to clarify discrete and continuous variation. Gender and eye color are given as examples of discrete variation, where traits are controlled by a small number of alleles. Height is given as an example of continuous variation, where multiple independent factors influence the trait.
4. Finally, the definition emphasizes that only variations resulting from genetic constitutions can be inherited. This highlights an important aspect of variation, as not all differences between individuals are genetically based or can be passed on to future generations.

Overall, this definition adequately covers the core concepts of variation, provides examples for better understanding, and clarifies the inheritability aspect. It is comprehensive without being overly complicated. Therefore, it can be considered a good definition of variation.
