Question:

How does the process of natural selection affect Hardy-Weinberg equilibrium?

Solution:

Natural Selection: It is a process in which heritable variations help in the survival of an organism, enabling it to reproduce and give rise to a large number of offspring. There may be changes in the frequency of genes and alleles in future generations. It leads to the formation of new species. Hardy-Weinberg law states that the allelic frequencies in a population are stable and stay constant from generation to generation. Thus, natural selection is more inclined towards the variation whereas Hardy-Weinberg's law states that the frequency of a particular allele should be constant from generation to generation. Other factors which affect Hardy-Weinberg equilibrium are: 1) Gene migration 2) Genetic drift 3) Mutations 4) Recombination
