Problem: Smooth seeds (S) are completely dominant over wrinkled seeds (s). You cross a plant that is homozygous for smooth seeds (male) with a plant that is heterozygous for smooth seeds (female). Use a Punnett square to determine the expected genotypic and phenotypic ratios for the offspring.
What is the phenotypic ratio of the offspring?
- 3 smooth: 1 wrinkled
- 1 smooth: 0 wrinkled
- 0 smooth: 2 wrinkled
- 1 smooth: 3 wrinkled
