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.

Key Discoveries
One of Barbara's most important discoveries was about genes that could move, or "jump," within the DNA of corn plants. 🌟This means that a gene in one place could suddenly appear in another spot, affecting how the plant grows. She published her findings in 1950 but didn't get much recognition at first. 🌱However, her work was later celebrated, and today we know that jumping genes play a significant role in evolution and genetics! Barbara showed that genes are not static; they can change and adapt, helping species survive. 🧬
