Detailed explanation-1: -Height is an example of continuous variation-individuals can have a complete range of heights, for example, 1.6, 1.61, 1.62, 1.625 metres tall and so on.
Detailed explanation-2: -Height ranges from that of the shortest person in the world to that of the tallest person. Any height is possible between these two extremes. So it is called continuous variation.
Detailed explanation-3: -Height, weight, temperature and length are all examples of continuous data.
Detailed explanation-4: -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. Continuous variation fluctuates around an average or a mean of species.
Detailed explanation-5: -Unlike a simple Mendelian characteristic, human height displays: Continuous variation. Unlike Mendel’s pea plants, humans don’t come in two clear-cut “tall” and “short” varieties. In fact, they don’t even come in four heights, or eight, or sixteen.
