Learning objectives

  • Calculate and interpret allele frequencies.
  • Compare selection, drift, migration and mutation.
  • Connect genotype frequencies to visible phenotypes.
  • Explain founder effects and bottlenecks.

Suggested experiments

  • Compare drift in populations of 12 and 120.
  • Reverse the direction of selection.
  • Raise migration between two habitats.
  • Set all forces near zero and observe random mating.
