Which of the following is NOT a condition for Hardy-Weinberg Equilibrium?

According to the Hardy-Weinberg equilibrium, if no unfavorable influences exist, genetic variation in a population will remain stable from one generation to the next. Furthermore, because genotype and allele frequencies are in equilibrium when mating is random in a large population with no disruptive influences, the rule predicts that they will remain constant.
• When a population reaches Hardy-Weinberg equilibrium for a gene, it is not evolving, and allele frequencies do not alter over time.
• The five fundamental Hardy-Weinberg assumptions are that there is no mutation, random mating, no gene flow, an infinite population size, and no selection.
• A gene's population may evolve (the allele frequencies of the gene may change) if the presumptions are not true for that gene.
