It looks like you're presenting a genetic problem involving flower and seed colors, where different phenotypes are associated with specific letter combinations. You have codes for flower color (P, p) and seed characteristics (S, s, G, g) and you have a list of phenotypes.
To clarify the notation, let's outline what the letters stand for again:
- **P** (Purple Flower) - Dominant
- **p** (White Flower) - Recessive
- **S** (Yellow Seed) - Dominant
- **s** (Green Seed) - Recessive
- **G** (Green Pod) - Dominant
- **g** (Yellow Pod) - Recessive
From your list of phenotypes provided, you have:
1. Yellow pod
2. Purple flower
3. White flower
4. Yellow seed (2 occurrences)
5. Green pod (2 occurrences)
6. Purple flower (again)
7. Yellow seed
8. Green pod
9. Purple flower
10. Yellow seed
11. Yellow pod (should correspond to recessive g)
### Parent Generation:
Assuming those are the offspring from a genetic cross, we can calculate the percentage of each genotype based on the number of occurrences of each phenotype.
### Count the Phenotypes:
From your list:
- For **Purple Flower** (P): Occurs 4 times.
- For **White Flower** (p): Occurs 1 time.
- For **Yellow Seed** (S): Occurs 4 times.
- For **Green Seed** (s): Not mentioned.
- For **Green Pod** (G): Occurs 3 times.
- For **Yellow Pod** (g): Occurs 2 times.
### Total Offspring Count:
In total, there are 11 plants counted from the list.
### Calculate Percentages:
Now we can calculate the percentages of each phenotype.
- **Homozygous Dominant (P, S, G)**: This includes plants that are homozygous for the dominant traits (e.g., P/S/G). These plants will exhibit traits for Purple flowers, Yellow seeds, and Green pods. You need to deduce the combinations.
- **Heterozygous Plants**: These include plants that have a combination of dominant and recessive genes (e.g., P/p, S/s, G/g).
- **Homozygous Recessive (p, s, g)**: These are the plants where both alleles are recessive.
To give the percentage for each category, we'd proceed with these calculations:
1. **Homozygous Dominant (Let's say all three traits are dominant)**:
- The plants with phenotype P, S, and G.
- Example: If at least one of the Purple Flower occurs from Homozygous Dominant.
2. **Heterozygous**:
- The plants that show dominant traits but are mixed (e.g., Pp, Ss, Gg).
3. **Homozygous Recessive** (count b) the instances of p, s, and g collectively.
### Concluding:
Please clarify how the specific combinations can be derived from the phenotypic expression and provide any counts or additional context so I can assist you in calculating the exact percentages. It seems you need to categorize the 11 total phenotypes and derive suitable percentages from there.
To clarify the notation, let's outline what the letters stand for again:

- **Heterozygous Plants**: These include plants that have a combination of dominant and recessive genes (e.g., P/p, S/s, G/g).
- **Homozygous Recessive (p, s, g)**: These are the plants where both alleles are recessive.
To give the percentage for each category, we'd proceed with these calculations:
1. **Homozygous Dominant (Let's say all three traits are dominant)**:
