For the relative proportions of alleles and genotypes in successive generations to remain constant (a condition known as Hardy-Weinberg equilibrium), one of the key conditions that must be met is the absence of natural selection. Natural selection acts on phenotypes (and thus genotypes) to change allele frequencies over time, which would disrupt the equilibrium.
