The tendency of population to remain in genetic equilibrium may be disturbed by

Step-by-step solution

According to Hardy-Weirberg principle, allele frequencies in a population are are stable and is constant from generation to generation allele frequencies in a population will remain constant over generations only if the following condition are met (i) There is no mutation no gene flow and all mating is random. (ii) All genotypes reproduce equally well (i.e., no natural selection). But, all there conditions rarely met in nature.
