How many pairs of contrasting characters were chosen by Mendel for his study with garden pea .

Options

A. 3
B. 5
C. 7
D. 14

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks how many pairs of contrasting characters Mendel chose for his study with garden pea.

2. **Identifying Mendel's Study**: Gregor Mendel conducted experiments using garden peas (Pisum sativum) to study inheritance patterns.

3. **Contrasting Traits**: Mendel selected specific traits that showed clear contrasting characteristics. These traits are typically dominant and recessive.

4. **Listing the Traits**: Mendel identified seven pairs of contrasting traits in his studies:
- **Stem Height**: Tall (dominant) vs. Dwarf (recessive)
- **Flower Color**: Purple (dominant) vs. White (recessive)
- **Pod Shape**: Inflated (dominant) vs. Constricted (recessive)
- **Pod Color**: Green (dominant) vs. Yellow (recessive)
- **Seed Shape**: Round (dominant) vs. Wrinkled (recessive)
- **Seed Color**: Yellow (dominant) vs. Green (recessive)
- **Flower Position**: Axial (dominant) vs. Terminal (recessive)

5. **Conclusion**: In total, Mendel chose **7 pairs of contrasting characters** for his study with garden peas.

6. **Final Answer**: The answer to the question is **C. 7**.
