Genes controlling seven traits in Pea studied by Mendel were actually located on

Options

A. Seven chromosomes
B. Six chromosomes
C. Four chromosomes
D. Five chromosomes

Answer

**Step-by-Step Solution:**

1. **Identify the Traits Studied by Mendel:**
Mendel studied seven traits in pea plants, which include seed color, flower color, plant height, pod color, pod shape, seed shape, and flower position.

2. **Determine the Chromosomes Associated with Each Trait:**
- **Seed Color and Flower Color:** These traits are located on chromosome number 1.
- **Height, Inflorescence, and Pod Shape:** These traits are located on chromosome number 4.
- **Pod Color:** This trait is located on chromosome number 5.
- **Seed Shape:** This trait is located on chromosome number 7.

3. **Count the Unique Chromosomes:**
From the above information, we can see that the seven traits are distributed across four different chromosomes:
- Chromosome 1 (seed color, flower color)
- Chromosome 4 (height, inflorescence, pod shape)
- Chromosome 5 (pod color)
- Chromosome 7 (seed shape)

4. **Conclusion:**
Therefore, the genes controlling the seven traits studied by Mendel are actually located on **four different chromosomes**.

**Final Answer:**
The genes controlling the seven traits in pea studied by Mendel were actually located on **four chromosomes** (chromosomes 1, 4, 5, and 7).
