Natural selection in which more individuals acquire peripheral character value at both the ends of the distribution curve is

Options

A. Stablising natural selection
B. Disruptive natural selection
C. Directional natural selection
D. The curve never shows the formation of two peaks

Answer

### Step-by-Step Solution

1. **Understanding Natural Selection**: Natural selection is a process where individuals with favorable traits are more likely to survive and reproduce. This leads to changes in the traits of a population over time.

2. **Distribution Curve**: In a population, traits can be represented on a distribution curve, where the x-axis represents the phenotypic traits and the y-axis represents the number of individuals exhibiting those traits.

3. **Types of Natural Selection**:
- **Stabilizing Selection**: This occurs when individuals with average traits are favored, leading to a peak at the mean value on the distribution curve. Here, extreme traits are selected against.
- **Directional Selection**: This occurs when individuals with traits at one end of the spectrum are favored, causing the peak of the distribution curve to shift towards that end.
- **Disruptive Selection**: This occurs when individuals at both extremes of the trait spectrum are favored, leading to a distribution curve with two peaks (one for each extreme).

4. **Identifying the Correct Type**: The question asks for the type of natural selection where more individuals acquire peripheral character values at both ends of the distribution curve. This description matches **disruptive selection**, as it involves favoring individuals with extreme traits rather than those with average traits.

5. **Conclusion**: Therefore, the answer to the question is **disruptive selection**.
