you will investigate the inheritance patterns of color and sweetness in zea mays. the kernel color (purple or yellow) in zea mays is controlled by the alleles p (purple) and p (yellow), with purple (p) being dominant. an additional trait of carbohydrate content (starchy or sweet) is controlled by the alleles s (starchy) and s (sweet), with starchy (s) being dominant. sweet kernels can be distinguished from starchy kernels because sweet kernels are wrinkled when they dry, and starchy kernels are smooth.
