Twenty cuttings were taken from one plant and planted in four containers of sand. two containers had a ph of 6.0, and two had a ph of 8.0. when the cuttings matured, all of those grown in a ph of 6.0 had pink flowers, and all of those grown in a ph of 8.0 had blue flowers. one explanation for these results is that the sand at one ph contained a dye that changed the flower color. the best alternative explanation for these results is that -

The difference in pH caused the genes for flower color to be expressed differently
