**Separated Species**

A population of mice lives in a light, sandy environment. The majority of mice have light-colored fur, and the remaining mice have either medium-colored fur or dark-colored fur. A flood occurs in the area, creating a river that separates the population and changes the color of the ground on either side. After a long period of time, the water dries up and the two groups of mice are able to interact again. After the change, mice from different sides are unable to breed with each other. The pictures show the environment before, during, and after the change.

**Images:**

1. **Original Environment**: Shows a flat, sandy landscape.
2. **Environments after separation by water**: Illustrates the North and South sides, divided by blue water, with varied landscapes.
3. **Environment after water dries up**: Displays a unified environment without water, showing similar terrain.

**Table: Frequency of fur color across populations after separation by water**

| Generation | North Side: Light | North Side: Medium | North Side: Dark | South Side: Light | South Side: Medium | South Side: Dark |
|------------|------------------|-------------------|-----------------|------------------|-------------------|-----------------|
| Generation 0 | 50% | 25% | 25% | 50% | 25% | 25% |
