It looks like there's a small typo in your message regarding the alleles for flower color in pea plants. The correct notation is typically:
- **P** for the dominant allele that produces purple flowers.
- **p** for the recessive allele that produces white flowers.
In pea plants, the inheritance of flower color follows Mendel's principles of dominance. Here’s a brief overview of how this works:
1. **Genotype**: The genetic makeup of an organism. For flower color, there are three possible genotypes:
- **PP**: Homozygous dominant (purple flowers)
- **Pp**: Heterozygous (purple flowers, since P is dominant)
- **pp**: Homozygous recessive (white flowers)
2. **Phenotype**: The observable traits of an organism. In this case:
- **Purple flowers** are the phenotype for both the **PP** and **Pp** genotypes.
- **White flowers** are the phenotype for the **pp** genotype.
3. **Punnett Square**: If you want to predict the offspring of a cross between two pea plants, you can use a Punnett square. For example, crossing **Pp** (purple) with **Pp** (purple) would yield:
| | P | p |
|---|---|---|
| P | PP | Pp |
| p | Pp | pp |
From this, the offspring phenotypic ratio would be:
- 3 purple (PP or Pp) : 1 white (pp).
