Which is not a dominant trait studies by Mendel ?

Options

A. Pod shape Inflated
B. Flower position Axial
C. Pod colour yellow
D. Seed shape round

Answer

To determine which trait is not a dominant trait studied by Mendel, we will analyze each of the given traits based on Mendelian genetics.

### Step-by-Step Solution:

1. **Identify the Traits**: The traits given in the question are:
- Pod shape (Inflated)
- Flower position (Axial)
- Pod color (Yellow)
- Seed shape (Round)

2. **Analyze Pod Shape**:
- The dominant trait for pod shape is "inflated."
- The recessive trait is "constricted."
- Since inflated is dominant, this option is not correct for our question.

3. **Analyze Flower Position**:
- The dominant trait for flower position is "axial."
- The recessive trait is "terminal."
- Since axial is dominant, this option is also not correct for our question.

4. **Analyze Pod Color**:
- The dominant trait for pod color is "green."
- The recessive trait is "yellow."
- Since yellow is recessive, this option is correct for our question.

5. **Analyze Seed Shape**:
- The dominant trait for seed shape is "round."
- The recessive trait is "wrinkled."
- Since round is dominant, this option is not correct for our question.

6. **Conclusion**:
- The trait that is not dominant among the options provided is **Pod color (Yellow)**, as it is a recessive trait.

### Final Answer:
The trait that is not a dominant trait studied by Mendel is **Pod color (Yellow)**.
