A : gene flow increases B : population size decreases C : mutation rate decreases D : the number of heterozygous loci increases E : population size increases WebDifferent alleles of genes are found within different individuals of a population. This is known as. Genetic variation. For a population to be in Hardy-Weinberg equilibrium, there must be no migration into or out of the population. Genetic variation in a population results from evolutionary forces that cause changes in.
