Why are corn cobs different colors?

The explanation lies in how different genes are expressed. These corncobs were part of Barbara McClintock’s studies on genetics and “jumping genes”. She showed that parts of the corn’s genetic code can shift from one place to another within its chromosomes. This is why corn kernels have different colours.
