Question

Mendel had chosen \_\_\_\_\_\_ pairs of contrasting characters for his study:

• A. 5
• B. 7
• C. 10
• D. 12

Hint:

Mendel studied 7 pairs of contrasting characters in pea plants to understand inheritance patterns.

Answer 1

The Correct Option is B

Step 1: Mendel's Experimental Setup.
Mendel conducted experiments on pea plants, where he selected seven pairs of contrasting traits (characters). These traits included flower color, seed shape, and plant height. Step 2: The Seven Traits.
The seven pairs of contrasting traits Mendel studied were:
1. Seed shape (round vs. wrinkled)
2. Seed color (yellow vs. green)
3. Flower color (purple vs. white)
4. Pod shape (inflated vs. constricted)
5. Pod color (green vs. yellow)
6. Flower position (axial vs. terminal)
7. Plant height (tall vs. short)
Step 3: Conclusion.
Therefore, Mendel had chosen 7 pairs of contrasting characters for his study.
