A scientist attempts to maintain a population of pea plants in a "non-evolving state" by trying to simulate the conditions required for Hardy-Weinberg equilibrium. He places the plants in a contained area under controlled conditions (no factors limiting) and makes certain that all crosses conducted are completely random. Which conditions for Hardy- Weinberg equilibrium have NOT been met?

no gene flow

no net mutations

random mating

no natural selection
