Genetic Drift

Random Genetic Drift
Describes the how genetic drift, one of the most important mechanisms of evolution, works.

Wikipedia: Genetic Drift
Hyperlinked article about the mechanism of evolution that acts in concert with natural selection to change the characteristics of species over time.

Genetic Drift and the Founder Effect
Brief hyperlinked article about the founder effect, the loss of genetic variation when a new colony is formed by a very small number of individuals, an extreme example of genetic drift.

Genetic Drift Simulation
Activity designed to help students visualize evolution at a simple level and develop their intuition for the process of genetic drift.

Small Population Size Effects: Genetic Drift
Describes the phenomenon acting on small, reproductively isolated populations that can produce rapid changes in gene frequencies totally independent of mutation, recombination, and natural selection.

Evolution 101: Genetic Drift
One of the basic mechanisms of evolution, genetic drift affects the genetic makeup of a population through an entirely random process.

Genetic Drift Workbook
Simulates the process of evolutionary change by genetic drift.
