The genes controlling seven traits in pea studied by Mendel were later found to be located on following number of chromosomes

Options

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

Answer

To solve the question regarding the number of chromosomes that control the seven traits studied by Mendel in peas, we can follow these steps:

### Step-by-Step Solution:

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

2. **Locate the Chromosomes for Each Trait**:
- **Chromosome 1**: Contains the genes for seed color and flower color.
- **Chromosome 4**: Contains the genes for height, inflorescence, and pod shape (3 traits).
- **Chromosome 5**: Contains the gene for pod color.
- **Chromosome 7**: Contains the gene for seed shape.

3. **Count the Unique Chromosomes**:
- From the above information, we can summarize the chromosomes:
- Chromosome 1: 2 traits (seed color, flower color)
- Chromosome 4: 3 traits (height, inflorescence, pod shape)
- Chromosome 5: 1 trait (pod color)
- Chromosome 7: 1 trait (seed shape)

4. **Total Number of Chromosomes**:
- The total number of unique chromosomes involved in these traits is 4 (Chromosomes 1, 4, 5, and 7).

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

### Final Answer:
The genes controlling the seven traits in pea studied by Mendel were later found to be located on **4 chromosomes**.
