A pea plant with purple flowers was crossed with white flowers producing 60 plants with only purple flowers.
On selfing, these plants produced 482 plants with purple flowers and 162 with white flowers. What gametic mechanism accounts for these results.

Explanation

To solve the problem, we need to analyze the genetic mechanism behind the flower color inheritance in pea plants. Here’s a step-by-step breakdown:

### Step 1: Identify the Traits
- **Purple flowers** are dominant (represented as **P**).
- **White flowers** are recessive (represented as **p**).

### Step 2: Initial Cross
- A pea plant with purple flowers (P) is crossed with a plant with white flowers (p).
