A species spread over a large tract with varied enviornmental conditions will have

Options

A. higher genetic diversity
B. uniform gene pool
C. little genetic diversity
D. both (2) and (3)

Answer

To solve the question regarding a species spread over a large tract with varied environmental conditions, we can break down the reasoning step by step:

### Step-by-Step Solution:

1. **Understanding Biodiversity**: Begin by defining biodiversity, which refers to the variety and variability of life on Earth. It encompasses three levels: genetic diversity, species diversity, and ecosystem diversity.

2. **Focus on Genetic Diversity**: Since the question specifically asks about a species spread over a large area with varied environmental conditions, we need to focus on genetic diversity. Genetic diversity refers to the variety of genes within a species.

3. **Impact of Varied Environmental Conditions**: A species that occupies a large area with diverse environmental conditions is likely to encounter different challenges and opportunities. This variation in the environment can lead to different adaptations within the species.

4. **Adaptation and Genetic Variation**: Higher genetic diversity within a species allows for better adaptation to changing environments. This means that individuals within the species may possess different traits that can help them survive and reproduce in varying conditions.

5. **Conclusion**: Therefore, a species spread over a large tract with varied environmental conditions will have higher genetic diversity. This leads us to select the first option as the correct answer.

### Final Answer:
The correct answer is **higher genetic diversity** (Option 1).
