Which of the following must be true of a population in genetic equilibrium?

Random mating is the correct answer

random mating The gene pool of a population is said to be in Hardy-Weinberg equilibrium if there is no migration in or out of the population (no gene flow), There are no mutations, no natural selection, The population is large enough to avoid genetic drift and the mating is random (e. g. not sexual selection) Let me know if I missed anything I learned this last year so I am by no means an expert.
