The procedure is similar to that for Case I Start again with your initial genotype and produce your as you did for Case I. Enter all data in 1. “offspring” Tables 3a and 3b. This time, however, there is one important difference. Every time your is aa, it “offspring” does not reproduce. Since we want to maintain a constant population size, the same two parents must try again until they produce two surviving offspring. You may need to get new cards from the pool, allowing “allele” each individual to complete the activity. 2. Proceed through five generations, selecting against the homozygous recessive offspring 100% of the time. 3. Add up the genotype frequencies that exist in the population and calculate the new p and q frequencies in the ame way that you did for Case I. Table 3a: Individual Genotype Table 3b: Class Totals Your Class Totals for Each Genotype Generation Genotype Generation AA Aa aa Initial (P) Aa F1 F1 F2 F2 F3 F3 F4 F4 F5 F5 Final Allele Frequency: The allele frequencies, p and q, should be calculated for the population after five generations of simulated random mating. Number of A alleles present at the fifth generation Number of offspring with genotype AA ________ x 2 = ______ A alleles
