Corn is bred for traits that improve its usefulness for specific purposes. Forexample, it may be bred to grow in various climates, to produce more corn, or tobe better tasting. These traits depend on the alleles inherited by the corn plant.Suppose that you are studying the color and texture of kernels on a cob. Kernelscan be either purple (R), which is the dominant color, or yellow (r), which is therecessive color. Kernels can also be smooth (T), which is the dominant texture, orwrinkled (t), which is the recessive texture. In this lab, you will predict theinheritance of alleles for two particular traits in a dihybrid cross by using aPunnett square.
