Hardy-Weinberg Equilibrium Model

Activity Summary
Students test different individuals’ ability to taste PTC (phenylthiocarbamide) to demonstrate the Hardy-Weinberg principle. Students will also test the genotype frequencies of an ideal population across generations and examine how selection, heterozygote advantage, and genetic drift change the genotype frequencies.

Grade Levels

2. Identify seven conditions that are needed for evolution to NOT occur in a population
3. Explain the mechanisms of evolution
4. Be able to use the Hardy-Weinberg equation
