NEED HELP! EXTRA POINTS!!!

Complete the Punnett square for the cross between two plants that are heterozygous for seed shape (Ss) and seed color (Gg). Smooth is dominant to wrinkled and green is dominant to yellow. Determine the phenotypic ratio for the offspring by determining the number of each of the phenotype combinations listed below (Hint: Follow the example answers that I gave for experiment 8.2).

Parental Phenotypes: x
Parental Genotypes: x
Parental Gametes: x




Smooth/green =
Wrinkled/green =
Smooth/yellow =
Wrinkled/yellow =

Answer 1

Parental Phenotypes: "Yellow-Smooth", "Yellow-Wrinkled", "Green-Smooth", "Green Wrinkled".

Parental Genotypes: SsGg × SsGg

Parental Gametes: SG, Sg, sG, sg

Smooth/Green = S-G- = 9

Winkled/Green = ssG- = 3

Smooth/Yellow = S-gg = 3

Wrinkled/Yellow = ssgg = 1

Ratio would be: 9: 3: 3: 1

Hope this helps!
