4. Predict Suppose corn plant C has a known genotype of RRTT. Could corn plants with cobs that had some yellow and wrinkled kernels be produced by crossing Plant C with a plant with a genotype of your choice? Why or why not?

Question
Corn is bred for traits that improve its usefulness for specific purposes. For
example, it may be bred to grow in various climates, to produce more corn, or to
be 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. Kernels
can be either purple (R), which is the dominant color, or yellow (r), which is the
recessive color. Kernels can also be smooth (T), which is the dominant texture, or
wrinkled (t), which is the recessive texture. In this lab, you will predict the
inheritance of alleles for two particular traits in a dihybrid cross by using a
Punnett square.
