Which of the following will impact a populations equilibrium ? . Random Mating
. No mutations
. Small population
. No Migration

". Small population"

Explanation:

      The conditions to maintain the (Hardy-Weinberg) equilibrium are no mutation, no gene flow, a large population size, random mating, and no natural selection. This can be disrupted by changes from any of its five main factors. No migration, no mutations, and random mating are all a part of this equilibrium, so the answer will be a small population.

Have a nice day!

     I hope this is what you are looking for, but if not - comment! I will edit and update my answer accordingly. (ノ^∇^)
