Continuous variation

Continuous variation occurs where individual phenotypes are impossible to distinguish, as the phenotypes cannot be classified into distinct classes.

Continuous variation produces a bell shaped curve relationship of the sampling population. The continuous variation is due to a large number of genes influencing the phenotypes.

Examples of continuous variation include:

  • Eye colour
  • Height
  • Body weight
