In summer squash, white fruit color (W) is dominant over yellow fruit color (w) and disk-shaped fruit (D) is dominant over sphere-shaped fruit (d). If a squash plant pure breeding for white and pure breeding for disk-shaped fruit is crossed with a plant pure breeding for yellow, sphere-shaped fruit, what will the phenotypic and genotypic ratios be for:
the F1 generation?
the F2 generation?
