Population Bottleneck
A population bottleneck is a sharp reduction in population size that drastically reduces genetic diversity. This article explains how bottlenecks occur, how they drive genetic drift, and why their effects persist for generations.
Genetic Drift
Genetic drift is the random change in allele frequencies caused by chance events. This article explains how drift works, why it is strongest in small populations, and how bottlenecks and founder effects shape evolution.
