Which one is not a dominant trait amongst seven Pea traits chosen by Mendel ?

Options

A. Flower Colour- Purple
B. Pod Colour-Yellow
C. Shape of Seed- Round
D. Flower-Axial

Answer

To determine which trait is not dominant among the seven pea traits chosen by Mendel, we will analyze each of the provided options based on Mendel's findings.

### Step-by-Step Solution:

1. **Identify the Traits**: The question provides four traits to evaluate:
- Flower color (purple)
- Pod color (yellow)
- Shape of seed (round)
- Flower position (axial)

2. **Evaluate Flower Color**:
- Mendel identified purple flower color as a dominant trait. Therefore, this option is not the answer.

3. **Evaluate Pod Color**:
- Mendel classified yellow pod color as a recessive trait. The dominant trait for pod color was green. Hence, this option is a candidate for the answer.

4. **Evaluate Shape of Seed**:
- The shape of the seed being round was considered a dominant trait, while the wrinkled shape was recessive. Thus, this option is also not the answer.

5. **Evaluate Flower Position**:
- The axial position of the flower was recognized as a dominant trait, while the terminal position was recessive. Therefore, this option is not the answer.

6. **Conclusion**:
- After evaluating all options, the trait that is not dominant among the seven pea traits chosen by Mendel is **pod color yellow**.

### Final Answer:
Pod color yellow is not a dominant trait among the seven pea traits chosen by Mendel.
