If a yellow plant from the F₂ generation is crossed with a green plant from the F1 generation, what would be the green-to-yellow phenotype ratio?
(A) 1:1
(B) 3:1
(C) 1:0
(D) 1:3

In a species of peas, green (G) peas are known to be classically dominant over yellow (g) peas. A true breeding green plant and a true breeding yellow plant are crossed. The resulting F₁ generation is evaluated, and its phenotype distribution is shown in Table 1. Two green pea producing members of the F₁ generation are then crossed, and the resulting F₂ generation phenotype distribution is shown in Table 2.
