Genetic Drift - Definition, Examples and Causes

WebThe founder effect is another extreme example of drift, one that occurs when a small group of individuals breaks off from a larger population to establish a colony. The new colony is isolated from the original population, and the founding individuals may not represent the full genetic diversity of the original population. WebGenetic drift can cause big losses of genetic variation for small populations.
