Is Heart Rate Continuous or Discontinuous Variation?

Examples of continuous variation include height, weight, heart rate, finger length, leaf length, etc. Examples of discontinuous variation include tongue rolling, finger prints, eye colour, and blood groups.

What are examples of discontinuous variation?

Human blood groups are an example of discontinuous variation. In the ABO blood group system, only four blood groups are possible - A, B, AB or O. You cannot have a blood group in between these four groups, so this is discontinuous variation.

How do you distinguish between continuous and discontinuous variation?

The main difference between continuous and discontinuous variation is that continuous variation shows an unbroken range of phenotypes of a particular character in the population whereas discontinuous variation shows two or more separate forms of a character in the population.
