Students explore natural selection and the way in which environmental change affects the genetic traits of a population. They also examine the Hardy-Weinberg principle and the concept of genetic equilibrium.
Students explore natural selection and the way in which environmental change affects the genetic traits of a population. They also examine the Hardy-Weinberg principle and the concept of genetic equilibrium. Using models of peppered moths, students conduct a series of experiments, changing the environmental variables and recording the results. They calculate the allelic, genotypic, and phenotypic frequencies for several generations of moths. These activities guide students to understand how environmental change can influence the allelic frequencies for a population over time. This kit contains enough materials for 30 students working in groups of 3 and includes a teacher's manual with reproducible student guide.
