In snapdragons, many flower colors are observed. In a cross between two true-breeding strains, one crimson and the other white, all of the F1 plants were rose color. In the F2, four new phenotypes appeared along with the P1 and F1 parental colors. The following ratio was obtained: 1/16 crimson, 4/16 rose, 2/16 orange, 2/16 pale yellow, 1/16 yellow,  4/16 white, and 2/16 magenta.
