The relationship of Ac/Ds in the control of the elements and mosaic color of maize. The seed in 10 is colorless; there is no Ac element present, and Ds inhibits the synthesis of colored pigments called anthocyanins. In 11 to 13, one copy of Ac is present; Ds can move, and some anthocyanin is produced, creating a mosaic pattern. In the kernel in panel 14 there are two Ac elements, and in panel 15 there are three.
