During his experiments with pea plant , which of the following characteristics was not used by Mendel ?

Options

A. Seed Colour
B. Seed Shape
C. Pod length
D. Pod shape

Answer

To determine which characteristic Mendel did not use during his experiments with pea plants, we need to first identify the traits he actually selected.

### Step-by-Step Solution:

1. **Identify the Subject of Mendel's Experiments**: Mendel conducted his experiments using the pea plant, scientifically known as *Pisum sativum*.

2. **List the Traits Mendel Selected**: Mendel selected seven specific traits to study in pea plants. These traits are:
- Color of flower
- Position of flower
- Color of seed
- Shape of seed
- Color of pod
- Shape of pod
- Stem length

3. **Analyze the Options Given**: The question asks which characteristic was not used by Mendel. We need to compare the options provided in the question with the traits he selected.

4. **Identify the Trait Not Used**: Among the traits Mendel studied, he included the shape of the pod but did not include the length of the pod. Therefore, if the option mentions "length of the pod," this is the characteristic that Mendel did not use.

5. **Conclusion**: The correct answer is the length of the pod, as it was not one of the seven traits Mendel selected for his experiments.

### Final Answer:
Mendel did not use the length of the pod in his experiments.
