In tomatoes, the three mutant traits, dwarfness, green flesh, and white flowers, are due to the homozygous recessive state of the genes d, gf, and wf (respectively). A dwarf, green-fleshed, white-flowered plant is crossed as the pollen parent to the homozygous normal plant.

a. Diagram the cross, using the forked-line method, to determine the F2 phenotypic ratio. Include phenotypes with the appropriate expected ratios.

b. If the F1 were testcrossed, what would be the expected phenotypic and expected genotypic ratios?
