Two local population becomes sister population when :-

Options

A. They have same species
B. They have different species
C. They lives in same habitat
D. (2) and (3) both

Answer

To determine when two local populations become sister populations, we need to understand the concept of sister populations in ecology. Here’s a step-by-step solution:

### Step-by-Step Solution:

1. **Definition of Sister Populations**: Sister populations refer to different local populations of the same species that are geographically separated but share a common ancestry.

2. **Same Species Requirement**: For two local populations to be classified as sister populations, they must belong to the same species. This means they share similar genetic and biological characteristics.

3. **Geographical Separation**: Although sister populations can be found in different habitats or geographical locations, they must still be part of the same species. For example, one population might be located in the northern region of a city, while another is in the southern region, but both belong to the same species.

4. **Conclusion**: Therefore, the correct condition for two local populations to be considered sister populations is that they must have the same species.

### Final Answer:
Two local populations become sister populations when they have the same species.
