Most people equate wealth with success. Dad and I had a huge argument because he equated my unemployment with laziness.
Market equilibrium is the state in which the quantity of a good or service demanded by consumers equals the quantity supplied by producers, resulting in a stable market price. At this point, there is no incentive for price to change, as the forces of supply and demand are balanced. If the price deviates from this equilibrium, market forces will typically drive it back to equilibrium through adjustments in demand and supply.
The Hardy-Weinberg equilibrium can be disrupted by deviations from any of its five main underlying conditions. Therefore mutation, gene flow, small population, nonrandom mating, and natural selection will disrupt the equilibrium.
