Zoology - Evolution Question with Solution | TestHub

Gene migration or gene flow is one of the factors affecting Hardy-Weinberg principles. When a population is following the principle and staying in equilibrium, it is not evolving. Thus, the allele frequencies will not change throughout different generations. Gene migration is movement of species out of a population or going into it causing change in the gene pool, thus breaking the equibrium. Gene flow does not help in maintaining the equilibrium.
