Long before they understood why the strategy worked, farmers knew how to crossbreed plants to obtain more desirable traits. Even today, a farmer who knows nothing about genetics can tell you that when a blue type of corn crosses with a yellow one, the offspring are blue. However, the farmer might add, if you cross a corn plant with small ears with a large-eared one, the offspring will have ears that are intermediate in size. Without any knowledge of genetics, the farmer has just told you a great deal about how the genes for blue color and ear size work. Included in this free selection from Garden Genetics: Teaching With Edible Plants (Student Edition) is an activity for students. You will also find a Contents and Introduction section.
