🌱 Understanding How Populations Change
This worksheet helps students explore how gene flow (the movement of alleles between populations) and genetic drift (random changes in allele frequencies) influence evolution. Through structured questions and real-world scenarios, students analyze how migration, population size, and chance events can shape genetic diversity over time. This resource strengthens conceptual understanding of evolution beyond natural selection and fits seamlessly into genetics, evolution, and population biology units.
