Which evolutionary outcome resulted when early Mesoamerican farmers selectively bred maize over generations?

💡 Explanation

When farmers selected for easier harvesting, a mutation inhibiting kernel shattering became advantageous because it prevented seeds from naturally dispersing before collection. Therefore, kernel shattering inhibition resulted, rather than drought resistance, nitrogen fixation, or increased cellulose, which depend on different genetic pathways and environmental pressures.
