The genes controlling the seven pea characters studied by mendel are now investigated by Blixt, to be located on four different chromosomes which are

Options

A. 2,3,1,1
B. 1,4,5,7
C. 1,2,3,7
D. 1,3,4,7

Explanation

To solve the question regarding the genes controlling the seven pea characters studied by Mendel and their location on different chromosomes, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Seven Contrasting Traits Studied by Mendel**:
Mendel studied seven traits in pea plants, which include:
- Seed color
- Flower color
- Plant height
- Pod shape
- Pod color
- Seed shape
- Flower position

2. **Determine the Chromosome Locations**:
According to Blixt's investigation, these traits are located on four different chromosomes. We need to assign each trait to its respective chromosome:
- **Chromosome 1**: Seed color and Flower color
- **Chromosome 4**: Plant height, Inflorescence (flower position), and Pod shape
- **Chromosome 5**: Pod color
- **Chromosome 7**: Seed shape

3. **List the Chromosomes with Their Traits**:
- Chromosome 1: Seed color, Flower color
- Chromosome 4: Plant height, Inflorescence, Pod shape
- Chromosome 5: Pod color
- Chromosome 7: Seed shape

4. **Select the Correct Answer**:
From the options provided, we need to identify which one corresponds to the chromosomes identified:
- The correct chromosome numbers based on the traits are 1, 4, 5, and 7.

5. **Conclusion**:
Therefore, the genes controlling the seven pea characters studied by Mendel are located on chromosomes 1, 4, 5, and 7.

### Final Answer:
The genes controlling the seven pea characters studied by Mendel are located on chromosomes **1, 4, 5, and 7**.
