In a population, if individulas with extreme properties die and only individulas with average property live, then the selection operating on this population will be :

Options

A. Stabilizing selection
B. Directional slection
C. Diversifying selection
D. Disruptive selection

Answer

To solve the question regarding the type of selection operating in a population where individuals with extreme properties die and only those with average properties survive, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Selection Types**: Begin by understanding the different types of natural selection:
- **Stabilizing Selection**: Favors average or intermediate traits and selects against extreme traits.
- **Directional Selection**: Favors one extreme phenotype over others, leading to a shift in the population's traits.
- **Disruptive Selection**: Favors individuals at both extremes of the trait spectrum while selecting against average traits.
- **Diversifying Selection**: Similar to disruptive selection, it favors extreme traits and can lead to speciation.

2. **Analyzing the Given Scenario**: The question states that individuals with extreme properties die, and only those with average properties survive. This indicates that the selection is favoring the average traits.

3. **Identifying the Correct Type of Selection**: Since the scenario describes a situation where extreme traits are not favored and average traits are favored, it aligns perfectly with the definition of stabilizing selection.

4. **Conclusion**: Based on the analysis, the selection operating on this population is **stabilizing selection**.

### Final Answer:
The correct answer is **stabilizing selection**.
