The yellow () gene encodes an enzyme that produces a yellow pigment. The red gene (R) encodes an enzyme that produces a red pigment. A third gene encodes an inhibitory enzyme When a dominant copy of I is present (II or li), the resulting protein inhibits the enzymatic activity of the red gene product. In the absence of both pigments, the flowers have white petals. (I).
