College Biology Instructor Guide


College Instructor edition with 26 experiments covering introductory and general biology topics.

Evolution & Population

Lab Summary

Use the Hardy-Weinberg equations to solve genetics problems.


Students investigate Hardy-Weinberg equilibrium and deviations from Hardy-Weinberg equilibrium. Students:

  • Calculate the frequencies of alleles and genotypes in a gene pool of a population using the Hardy-Weinberg equations.
  • Using the class as a sample population, study the relationship between microevolution and changes in allele frequency.


Students will gain experience conducting the following procedure:

  • Using the Hardy-Weinberg equations to answer genetics problems.
