In his classic experiments on pea plants Mendel did not use

Options

A. seed colour
B. pod length
C. seed shape
D. flower position

Answer

**Step-by-Step Solution:**

1. **Understanding Mendel's Experiments**: Gregor Mendel conducted experiments on pea plants (Pisum sativum) to study inheritance patterns. He selected specific traits to analyze how they were passed from one generation to the next.

2. **Identifying the Traits Used by Mendel**: Mendel focused on seven distinct traits in his experiments:
- Plant height (tall vs. dwarf)
- Flower position (axial vs. terminal)
- Pod color (green vs. yellow)
- Pod shape (inflated vs. constricted)
- Seed shape (round vs. wrinkled)
- Seed color (yellow vs. green)
- Flower color (violet vs. white)

3. **Analyzing the Given Options**: The question asks which trait Mendel did not use in his experiments. The options provided are:
- A) Seed color
- B) Pod length
- C) Seed shape
- D) Flower position

4. **Comparing Options with Mendel's Traits**:
- Seed color: Used by Mendel (yellow vs. green).
- Pod length: Not mentioned as one of the traits Mendel studied.
- Seed shape: Used by Mendel (round vs. wrinkled).
- Flower position: Used by Mendel (axial vs. terminal).

5. **Conclusion**: Since Mendel did not study pod length, the correct answer to the question is **B) Pod length**.
