Number of pairs of characters used by Mendal during his experiments were

Options

A. Ten
B. Six
C. Seven
D. Two

Answer

**Step-by-Step Solution:**

1. **Understanding Mendel's Work**: Gregor Mendel is known as the father of genetics for his pioneering work on inheritance patterns in pea plants.

2. **Identifying the Traits Studied**: Mendel selected specific traits to study the inheritance patterns. He focused on seven different traits in pea plants.

3. **Listing the Traits**: The seven traits Mendel studied include:
- Plant height (tall vs. dwarf)
- Flower color (purple vs. white)
- Flower position (axial vs. terminal)
- Pod shape (inflated vs. constricted)
- Pod color (green vs. yellow)
- Seed shape (round vs. wrinkled)
- Seed color (yellow vs. green)

4. **Counting the Pairs of Characters**: Each trait has two contrasting forms, which can be considered as pairs of characters. Therefore, Mendel used a total of 7 pairs of contrasting traits.

5. **Conclusion**: The number of pairs of characters used by Mendel during his experiments is 7.

**Final Answer**: 7
