Summary Introduction
To distinguish:
Between directional, disruptive and stabilizing selection.
Concept Introduction:
Charles Darwin gave the idea about natural selection which is an essential process of evolution. But, there are many more forces that bring change in the evolution. Natural selection supports the allele that causes successful reproduction and in the selection, besides those alleles that are not successful, it results for creating a population.
