For this activity, you will need the tables below and a pencil. Refer to your textbook as needed.
A farmer who raises vegetables wants to cross two types of corn plants. One type is a
homozygous plant with red kernels (RR) and the other is a homozygous plant with white
kernels (rr). For these plants, red color is dominant and white color is recessive. Create a Punnett square below to predict the offspring the farmer should expect.

1. Using the Punnett square, predict the color of the corn kernels. Will the plants produce
all red kernels, all white kernels, or a mixture of both colors?
all red kernels, all white kernels, or a mixture of both colors?
2. What would be the ratio of red corn to white corn in the offspring?
Next, the farmer cross-pollinates the red hybrid (Rr) offspring. Create a Punnett
square below for this cross.
