You have been studying flowers in a field in your neighborhood. The flowers come in two different colors, purple and white. The purple flowers seem to be more abundant in wetter soil, while the white flowers seem to occur in drier soil. You are sure that the flowers are the same species, but do not know what is causing the variation in flower color. Explain how you would determine the cause of the color variation in these flowers?
