BST 4) BETT White fruit color in summer squash is influenced by a dominant allele W, wiereas colored fruit must be ww. In the presence of ww, a dominant gene G results in yellow fruit, and if the individual had both recessive genes in the homozygous condition, it would be green. Give the F2 phenotypic ratios resulting from a cross of a pure-breeding white of genotype WW GG with a green.
