§The smaller the population, the less genetic variety it has. §In a very small population, alleles can be lost from one generation to the next, simply by random chance. §When a population evolves only because of this type of random sampling error, GENETIC DRIFT is taking place.

Genetic Drift Genetic drift is a random process that can be important in the evolution of some populations. One of the requirements for the maintenance of allele frequencies in populations is a very large population size. Genetic drift is the consequence of finite population size.

§A population that is NOT EVOLVING is said to be in Hardy-Weinberg equilibrium. §We can use HW calculations to measure microevolution in populations.

A2 Humans impact variation in other species. To foster student understanding of this concept, instructors can choose an illustrative example such as: • Artificial selection • Loss of genetic diversity within a crop species • Overuse of antibiotics

1. A. 3: Evolutionary change is also driven by random processes. a 1.A.3: Evolutionary change is also driven by random processes. a. Genetic drift is a nonselective process occurring in small populations. b. Reduction of genetic variation within a given population can increase the differences between populations of the same species
