Final answer:
The correct conditions for a population to be in Hardy-Weinberg equilibrium are no mutations and random mating, among others. Options A (no mutations) and B (random mating) are accurate descriptions of these conditions.
Step-by-step explanation:
For a population to be in Hardy-Weinberg equilibrium, several conditions must be met: A. no mutations, B. random mating, and E. occurrence of mutations are not correct descriptions of the conditions. Instead, the correct conditions are no mutations, no gene flow or migration, a large population size (not small), random mating, and no natural selection. Therefore, options A (no mutations) and B (random mating) accurately describe conditions that must be met for a population to be in Hardy-Weinberg equilibrium.
