Answer

To answer the question about the arrangement of Mendel's selected seven characters on four chromosomes, we can break it down into a step-by-step solution.

### Step-by-Step Solution:

1. **Understanding Mendel's Work**: Mendel studied pea plants and identified seven traits that were inherited. These traits are associated with specific chromosomes.

2. **Chromosome Count in Pea Plants**: Pea plants (Pisum sativum) have a total of 14 chromosomes, which means they have seven pairs of chromosomes.

3. **Distribution of Traits**: Mendel's seven traits are distributed across four chromosomes. The traits are as follows:
- From **Chromosome 1**: 2 traits
- From **Chromosome 4**: 3 traits
- From **Chromosome 5**: 1 trait
- From **Chromosome 7**: 1 trait

4. **Identifying the Traits**: The specific traits Mendel studied include:
- Seed shape (round or wrinkled)
- Seed color (yellow or green)
- Pod shape (inflated or constricted)
- Pod color (green or yellow)
- Flower position (axial or terminal)
- Flower color (purple or white)
- Stem length (tall or short)

5. **Correct Arrangement**: Based on the distribution, the correct arrangement of the traits on the chromosomes is:
- **Chromosome 1**: 2 traits
- **Chromosome 4**: 3 traits
- **Chromosome 5**: 1 trait
- **Chromosome 7**: 1 trait

6. **Conclusion**: The arrangement of Mendel's seven selected characters on four chromosomes is confirmed to be correct as per the distribution mentioned above.
