Population Genetics and Evolution: A Simulation Exercise

Webmutations, genetic drift, gene flow, and natural selection, are in effect. For introductory biology students, the types of changes associated with these microevolutionary forces are not readily observed through experimental exercises. Simulation activities provide the best means for reinforcing these topics at the introductory level. WebExperiment 2: Genetic Drift. Genetic drift, the variation in the gene pool and/or gene frequency of a population, can result from a variety of stochastic (random) events. … WebGenetic drift occurs in all populations of non-infinite size, but its effects are strongest in small populations.

WebNatural selection can cause a trait variation to become more or less common in a population over time. Natural selection requires variability, heritability, and reproductive advantage. Natural selection acts on random variations. Variations must pass from parent to offspring. 5 minutes. WebRun this simulation several times. What usually happens to the A 1 allele and why? Allele A1 is usually lost from the population; this is due to genetic drift. Note the red lines in the graph below.
