A gardener crosses a true-breeding tall tomato plant bearing red fruit with a true-breeding dwarf tomato plant with yellow truit. In tomatoes, tall vine (T) is dominant to dwart vine (t) and red fruit (1) is dominant to yellow fruit (1)
Assume that the two genes controlling the “tali vine“ and “red fruit" traits are on two different pairs of chromosomes.
What are the expected phenotype ratlos in the F2 generation?
A 9 tall vinatred fruit; 3 tal vine/yellow truit; 3 dwart vine/red fruit: 1 dwarf vine/yellow trult
B. 4 tall vine/red fruit, 3 tali vine/yellow fruit; 1 dwarf vinetred fruit
