Lab-Aids: Genetic Equilibrium & Natural Selection Kit
Students study the principles of genetic equilibrium and natural selection as a process of evolution using this kit. A simulation is used to develop insights about the genetic process involved when natural selection operates within a population in genetic equilibrium. Students use the data collected in the Hardy-Weinberg Equilibrium to understand better the actual complexity of natural selection. All material in this activity, for 30 students, is reusable.
Scientific Concepts:
- Understand the principles of genetic equilibrium and natural selection as a process of evolution
- Collect data from a simulated genetic process when natural selection is operating on a population in genetic equilibrium
- Use data in a Hardy-Weinberg Equilibrium
- Understand that gene frequencies in equilibrium will remain in equilibrium in the absence of mutation, migration, or selection
- Understand that natural selection operates against the less favorable phenotypes in a population resulting in a larger proportion of favorable phenotypes in subsequent generations
