White fruit color in summer squash is influenced by a dominant allele W, whereas colored fruit must be ww. In the presence of ww, a dominant gene G results in yellow fruit, and homozygous gg results in green fruit. The F2 phenotypic ratios resulting from a cross of a true-breeding plant with white fruit (genotype WW GG) with a plant with green fruit will result in which phenotypic ratios?
A. 8/16 white, 4/16 yellow, 4/16 green B. 12/16 white, 3/16 yellow, 1/16 green C. 4/16 white, 8/16 yellow, 4/16 green D. 12/16 white, 2/16 yellow, 2/16 green E. 8/16 white, 8/16 green
