White fruit color in summer squash is governed by a dominant gene (W) and colored fruit by its recessive allele (w). Yellow fruit is governed by gene (G) and green by its recessive allele (g). When

parents heterozygous for both alleles are crossed, the offspring appear in the ratio 12 white: 3

yellow: 1 green. What fruit color ratios are expected from the cross of WwGg x Wwgg?
