Which one of the following Mendelian traits is present on the fifth chromosome ?

Options

A. Pod shape
B. Pod color
C. Flowers color
D. Pod position

Answer

To determine which Mendelian trait is present on the fifth chromosome, we can follow these steps:

### Step-by-Step Solution:

1. **Understand Mendelian Traits**: Mendelian traits are characteristics that are inherited according to Mendel's laws of inheritance. Gregor Mendel studied these traits in garden peas (Pisum sativum) and identified seven contrasting traits.

2. **Identify the Seven Contrasting Traits**: The seven traits Mendel studied include:
- Pod shape (inflated vs. constricted)
- Pod color (green vs. yellow)
- Seed shape (round vs. wrinkled)
- Seed color (yellow vs. green)
- Flower color (purple vs. white)
- Flower position (axial vs. terminal)
- Stem height (tall vs. short)

3. **Locate Traits on Chromosomes**: Mendel's traits are not distributed across seven different chromosomes; instead, they are located on four chromosomes. The specific traits are assigned to specific chromosomes:
- Pod shape is located on the 4th chromosome.
- Pod color is located on the 5th chromosome.
- Flower color is located on the 1st chromosome.
- Flower position is also included in the traits.

4. **Identify the Trait on the Fifth Chromosome**: Since we are specifically looking for the trait located on the fifth chromosome, we can conclude that the trait associated with the fifth chromosome is **pod color**.

5. **Final Answer**: The Mendelian trait present on the fifth chromosome is **pod color**.
