Punnett Square:
First, let's create a Punnett square to determine the genotypes of the F1 generation.
| | Gg | Gg |
|---|------|------|
| Yy | GgYy | GgYy |
| Yy | GgYy | GgYy |
From the Punnett square, we can see that all of the F1 plants will be tall with green pods and heterozygous for both traits.
F1 Generation:
When the F1 plants are self-crossed, we can create another Punnett square to determine the genotypes of the F2 generation.
| | G | g |
|-----|----|----|
| Y | GY | gY |
| y | Gy | gy |
From the Punnett square, we can see that the F2 generation will have the following genotypic ratio:
- 1 GGYY : 2 GgYY : 1 ggYY : 2 GGyY : 4 GgyY : 2 ggyY : 1 GGyy : 2 Ggyy : 1 ggyy
Phenotypic Ratio:
Since we know that tall and green pod are dominant traits, we can determine the phenotypic ratio by adding up the genotypes that exhibit those traits:
- 9 tall plants with green pods
- 3 tall plants with yellow pods
- 3 short plants with green pods
- 1 short plant with yellow pod
Therefore, out of 16 F2 plants, 4 will be short (3 with green pods and 1 with yellow pod). The correct answer is option B.

- 1 GGYY : 2 GgYY : 1 ggYY : 2 GGyY : 4 GgyY : 2 ggyY : 1 GGyy : 2 Ggyy : 1 ggyy
Phenotypic Ratio:
Since we know that tall and green pod are dominant traits, we can determine the phenotypic ratio by adding up the genotypes that exhibit those traits:
- 9 tall plants with green pods
- 3 tall plants with yellow pods
- 3 short plants with green pods
- 1 short plant with yellow pod
Therefore, out of 16 F2 plants, 4 will be short (3 with green pods and 1 with yellow pod). The correct answer is option B.
