Genetic Drift

The video explores the concept of genetic drift, using Halloween candy as a metaphor for randomness and chance. It explains how genetic drift differs from natural selection, emphasizing that it is a random process affecting allele frequencies in populations. The video introduces the bottleneck and founder effects as examples of genetic drift and highlights the significant impact on small populations. The Amoeba Sisters conclude by encouraging curiosity.
