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

To determine the number of chromosomes that control the seven traits studied by Mendel in pea plants, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Traits**: Mendel studied seven distinct traits in pea plants. These traits include characteristics such as seed shape, seed color, flower color, pod shape, pod color, flower position, and plant height.

2. **Understand Chromosomal Basis**: Each trait is controlled by genes located on chromosomes. The number of chromosomes can vary, but Mendel's experiments indicated that multiple traits could be located on the same chromosome.

3. **Analyze Chromosome Distribution**: According to the information provided, Mendel's seven traits are distributed across four chromosomes:
- Chromosome 1: 2 traits
- Chromosome 4: 3 traits
- Chromosome 5: 1 trait
- Chromosome 7: 1 trait

4. **Count the Chromosomes**: From the distribution, we see that all seven traits are accounted for by four chromosomes.

5. **Conclusion**: Therefore, the answer to the question is that the genes controlling the seven traits in pea plants studied by Mendel were actually located on **4 chromosomes**.

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