7-8. Assume that white color is dominant over yellow color in squash. If pollen from the anthers of a heterozygous white-fruited plant is placed on the pistil of a yellow- fruited plant, show using ratios the genotypes and phenotypes you would expect the seeds from this cross to produce. Genotypes = 1/2 Ww 1/2 Ww = 1:1 ratio | Phenotypes = All white = 1:0 ratio Genotypes = 1/2 WW 1/2 ww = 1:1 ratio | Phenotypes = 1/2 white 1/2 yellow = 1:1 ratio Genotypes = 3/4 Ww /4 ww = 1:1 ratio | Phenotypes = 3/4 white 1/4 yellow = 1:1 ratio Genotypes = 1/2 Ww 1/2 ww = 1:1 ratio | Phenotypes = 1/2 white 1/2 yellow = 1:1 ratio
