And clearly hair color, skin color and eye color all fall under the definition of a
continuous trait
, because even though they dont seem to be affected by the environment, they are definitely polygenic traits and show a gradation, so they’re definitely continuous traits.
Is eye Colour an example of continuous or discontinuous variation?
A characteristic of any species with only a limited number of possible values shows
discontinuous variation
. For example: eye colour.
Is eye Colour continuous?

What is continuous variation in simple words?
In other words, continuous variation is
where the different types of variations are distributed on a continuum
, while discontinuous variation is where the different types of variations are placed into discrete, individual categories. Examples of continuous variation include things like a person’s height and weight.
Can continuous variation be inherited?
Continuous variation of a character shows an unbroken range of phenotypes in the population. … In some continuous distributions all the variation is environmental and
has no genetic basis at all
. In other cases there is a genetic component caused by allelic variation of a small or a large number of genes.
What is the cause of continuous variation?
Differences in external environmental conditions
also produce continuous variation. In nature, each character will be influenced by many environmental variables, some tending to increase it, others to decrease it.
Do purple eyes exist?
