What conditions must be true for a population to remain in genetic equilibrium?
gene flow, genetic drift, sexual selection, population isolation, and no mutations
gene flow, random mating, no mutations, no genetic variation, and no natural selection
large population, sexual selection, gene flow, no mutations, and no natural selection
large population, random mating, no migration in or out, no mutations, and no genetic variation

D. Large population, random mating, no migration in or out, no mutations, and no genetic variation

Explanation:

This is because with random mating a species wont start to diversify slowly because of the separation of different groups among the species.

No migration because if the species could migrate then the group that migrated would slowly adapt to a new environment causing it to diversify.

No mutations because if an offspring is mutated and that mutated gene gets passed on, the species becomes diverse and no longer in genetic equilibrium.

And no genetic variation for obvious reasons.

Hope this helps!
