In tomatoes, tall vine (T) is dominant to dwarf vine (t), and red fruit (R) is dominant to yellow fruit (r). A gardener crosses a dihybrid tall tomato plant bearing red fruit with a true-breeding dwarf tomato plant with yellow fruit.

1. Describe the possible phenotypes and genotypes of the plants. Responses should include expected phenotype ratios. Explain your reasoning as needed.
2. If 100 of these tomato plant offspring were planted, how many plants would you predict you would find of each phenotype.
