Explanation / Answer

One of the tenants of natural selection is that within populations, variation exists amongst the individuals.

This variation is generated through mutation, recombination, independent assortment and gene flow.

Because only alleles that are phenotypically expressed are subject to the pressure of natural selection. Heterozygotes can be the protector of recessive alleles that could possibly be lost otherwise.

As long as the heterozygote survive, so do recessive alleles and their corresponding phenotypes which could possibly have greater fitnesses in a changing environment.

When natural selection favors the ratio of two or more phenotypes over multiple generations, it is called balanced polymorphism.
