(u. s. department of agriculture) only red-flowered plants are produced. If the white-flowered grandchildren are crossed with each other only white- flowered plants appear. But if the pink- flowered grandchildren are crossed with each other, the ofi"spring include plants with red flowers, plants with pink flowers, and plants with white flowers in the ratio of 1:2:1. You readily recog- nize that this is the same ratio that was obtained when pink-flowered plants were crossed before.
