**Title: Identifying the Genotypes of Pea Flower Plants for Each Generation**

**P Generation (True-breeding parents):**
- **Phenotypes:** 
  - Purple flowers
  - White flowers
- **Genotypes:**
  - Purple flowers: [Box labeled "1"]
  - White flowers: [Box labeled "2"]

Diagram: This section represents the parental generation. The purple flower and white flower cross, denoted by an 'x'.

**F1 Generation (Hybrids):**
- **Phenotypes:** 
  - All purple flowers
- **Genotypes:**
  - [Box labeled "3"]

Diagram: This section shows the result of the P generation cross, with only purple flowers appearing in the F1 generation.

**F2 Generation:**
- **Phenotypes:** 
  - Purple flowers
  - White flowers
- **Genotypes:**
  - Purple flowers: [Box labeled "4"]
  - White flowers: [Box labeled "5"]

Diagram: The F2 generation results from self- or cross-pollination of F1. It shows a mix of purple and white flowers.

This visual representation explains the principles of Mendelian inheritance by demonstrating the patterns of flower color inheritance in pea plants across three generations.
