Genetic Drift and Gene Flow
Exploring non-selective mechanisms that change allele frequencies in populations, such as bottleneck and founder effects.
Key Questions
- Explain how the 'founder effect' impacts the genetic diversity of isolated populations.
- Justify why genetic drift is more influential in small populations than large ones.
- Analyze how gene flow between populations prevents speciation.
