*Hint: Assume complete dominance

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 heterozygous squash plant is crossed with another heterozygous squash plant what will be the genotypic and phenotypic ratio?.

  1. 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 heterozygous squash plant is crossed with another heterozygous squash plant what will be the genotypic and phenotypic ratio? *Hint: Assume complete dominance

  2. Phenotypic Ratio 9/16 will have white, disk-shaped fruit 3/16 will have white, sphere-shaped fruit 3/16 will have yellow, disk-shaped fruit 1/16 will have yellow, sphere-shaped fruit …so the phenotypic ratio would be: 9:3:3:1 Genotypic Ratio 1/16 WWDD 2/16 WWDd 2/16 WwDD 1/16 WWdd 4/16 WwDd 2/16 Wwdd 1/16 wwDD 2/16 wwDd 1/16 wwdd …so the genotypic ratio would be: 1:2:2:1:4:2:1:2:1
