If nature selects both of the peripheral traits of a character then which kind of natural selection is said to be operating?

Options

A. Stabilsing
B. Disruptive
C. Directional
D. Rotating

Answer

To determine the type of natural selection that operates when both peripheral traits of a character are favored by nature, we can analyze the different types of natural selection:

### Step-by-Step Solution:

1. **Understanding Natural Selection**: Natural selection is the process by which certain traits become more or less common in a population due to their effects on the survival and reproduction of organisms.

2. **Types of Natural Selection**:
- **Directional Selection**: This type favors one extreme trait over others, leading to a shift in the population towards that trait. For example, if dark-colored fur is favored, the population will have more dark-colored individuals over time.
- **Stabilizing Selection**: This type favors the intermediate traits and reduces variation. It leads to a population where the average trait is more common, while extreme traits are selected against. For instance, if medium-colored fur is favored, the population will have more medium-colored individuals.
- **Disruptive (or Diversifying) Selection**: This type favors both extreme traits at the periphery, leading to a population where both extremes are more common than the intermediate trait. For example, if both light and dark-colored fur are favored, the population will have more individuals with these colors, resulting in two peaks in the trait distribution.

3. **Analyzing the Question**: The question states that nature selects both peripheral traits of a character. This indicates that both extremes are being favored rather than just one or the average.

4. **Conclusion**: Since both peripheral traits are being selected, this scenario corresponds to **disruptive (or diversifying) selection**. Therefore, the answer is **disruptive selection**.

### Final Answer:
Disruptive selection (Option B).
