Which is not true regarding genetic diversity?

Options

A. It enables a population to adapt to its environment.
B. It is also the basis of speciation.
C. Ecotype formation depends upon it.
D. Higher diversity increases uniformity

Answer

**Step-by-Step Solution:**

1. **Understanding Genetic Diversity**: Genetic diversity refers to the variety of genes within a species. It is crucial for the adaptability and survival of populations in changing environments.

2. **Analyzing the Options**:
- **Option 1**: "It enables a population to adapt to its environment."
- This statement is true. Genetic diversity allows populations to adapt to environmental changes through natural selection.

- **Option 2**: "It is also the basis of speciation."
- This statement is true. Genetic diversity contributes to the formation of new species through evolutionary processes.

- **Option 3**: "Ecotype formation depends upon it."
- This statement is true. Ecotypes are distinct forms of a species adapted to specific environmental conditions, and they arise from genetic diversity.

- **Option 4**: "Higher diversity increases uniformity."
- This statement is false. Higher genetic diversity actually leads to greater heterogeneity, not uniformity. It results in a wider range of traits within a population.

3. **Conclusion**: The statement that is not true regarding genetic diversity is **Option 4: "Higher diversity increases uniformity."**

**Final Answer**: Option 4 is not true regarding genetic diversity.
