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: -Continuous Variation There is no fixed point at which someone becomes short or tall. Instead, height can range from very short to very tall and everything in between . It is continuous because a person’s height can be a wide range of different values (e.g. 1.7m, 1.71m, 1.72m, 1.725…) .
Detailed explanation-3: -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.
Detailed explanation-4: -Examples of continuous variation include things like a person’s height and weight. Examples of discontinuous variation include a person’s blood group or the color of a species of bird.
