A Geneticist’s Growing Season

What does a maize geneticist do? Explore the growing season of maize, and how scientists study the plant’s genetic diversity and connect it to the phenotypes they observe. Maize needs lots of sun and warm weather to grow. Seeds are usually planted in spring, in marked rows to identify each plant by its pedigree and genotype. In the mid-summer, when the plants are ready, scientists begin crossing the varieties of maize.
