● natural selection. Answer: differential reproduction or non-random
reproduction due to differential survival in the face of natural selection
predators like a changing biotic (e.g., pathogens, predators, food) or
abiotic environment (e.g., weather).
● gene flow. Answer: alleles move between populations due to
individuals migrating or individuals from different populations meeting
up to reproduce.
● genetic drift. Answer: random causes such as rare alleles disappearing
in a small population due to the 50% chance that the gamete of a diploid
organism contains one allele or the other, or random death due to a
