Which one of the following trait of pea plants studied by mendel is dominant?

Options

A. Green pod colour
B. Yellow pod colour
C. White pod colour
D. Terminal pod colour

Answer

To determine which trait of pea plants studied by Mendel is dominant, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Traits Studied by Mendel**: Mendel studied seven contrasting traits in pea plants. These traits include:
- Seed shape (round vs. wrinkled)
- Seed color (yellow vs. green)
- Pod shape (inflated vs. constricted)
- Pod color (green vs. yellow)
- Flower color (purple vs. white)
- Plant height (tall vs. dwarf)
- Flower position (axial vs. terminal)

2. **Determine Dominant and Recessive Traits**: For each trait, Mendel identified which was dominant and which was recessive:
- Seed shape: Round (dominant) vs. Wrinkled (recessive)
- Seed color: Yellow (dominant) vs. Green (recessive)
- Pod shape: Inflated (dominant) vs. Constricted (recessive)
- Pod color: Green (recessive) vs. Yellow (dominant)
- Flower color: Purple (dominant) vs. White (recessive)
- Plant height: Tall (dominant) vs. Dwarf (recessive)
- Flower position: Axial (dominant) vs. Terminal (recessive)

3. **Analyze the Given Options**: The question provides options, and we need to identify which one corresponds to a dominant trait. The options are:
- A) Green pod color
- B) Yellow pod color
- C) Green seed color
- D) Dwarf plant height

4. **Match Options with Dominant Traits**:
- **Green pod color**: This is a recessive trait.
- **Yellow pod color**: This is a dominant trait.
- **Green seed color**: This is a recessive trait.
- **Dwarf plant height**: This is a recessive trait.

5. **Select the Correct Answer**: Based on the analysis, the dominant trait among the options provided is **Yellow pod color**.

### Final Answer:
The dominant trait of pea plants studied by Mendel is **Yellow pod color** (Option B).
