1. **Genetic drift** - Over time, a series of random occurrences can cause an allele to become more or less common in a population, and this phenomenon is referred to as genetic drift.
2. **Bottleneck effect** - When a population is severely reduced by an environmental disaster such as a fire, the result is a bottleneck effect due to the reduced genetic diversity of the survivors.
3. **Founder effect** - The founder effect can occur if a small group of organisms migrates to a new location and becomes isolated from the rest of the population.
