AP Biology Lab 8: Population Genetics and Evolution Pre-Lab Questions: 1. How does natural selection alter allelic frequencies in a population? 2. What is the Hardy-Weinberg equation? How is it used in determining the frequency of alleles in a population? 3. What is the effect on allelic frequencies of selection against the homozygous recessive or other genotypes? Question: How do you calculate the allelic frequency and genotypes in the gene pool of a population using Hardy-Weinberg formula? What conditions must be met for a population to be in equilibrium? How does natural selection and microevolution deviate from the conditions required to maintain Hardy-Weinberg equilibrium? Hypothesis: Dependent Variable: Independent Variable: Experiment Design: Control Treatment:
