Population is a group of individuals of a single species living in a given area. It includes spatial arrangement, genetic variation and the dynamics including natality, mortality, biotic potential, carrying capacity, etc. Population structure includes features as density, abundance, spacing, genetic variations. The genetic structure reveals genetic variations and population size.
_______species inhabit different geographical areas. Allopatric.

Options

A. Sympatic
B. Allopatric
C. Both (A) and (B)
D. None of these

Explanation

To answer the question regarding species that inhabit different geographical areas, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Population**: Begin by defining what a population is. A population consists of individuals of the same species living in a specific area. This includes their spatial arrangement, genetic variation, and dynamics such as birth rates (natality), death rates (mortality), and other ecological factors.

2. **Identifying Species Types**: The question asks about species that inhabit different geographical areas. To answer this, we need to differentiate between types of species based on their geographical distribution.

3. **Sympatric Species**: Sympatric species are those that live in the same geographical area and can interbreed. Since the question specifies species in different geographical areas, this term is not applicable.

4. **Allopatric Species**: Allopatric species are those that are geographically isolated from one another. They do not interbreed because they are separated by physical barriers, leading to a lack of gene flow between them. This fits the description of species that inhabit different geographical areas.

5. **Conclusion**: Based on the definitions and distinctions made, the correct term for species that inhabit different geographical areas is "Allopatric species."

### Final Answer:
**Allopatric species inhabit different geographical areas.**
