Part 3: Selection Selection can be for or against a particular phenotype. In this part, you'll look at both. 1. To examine heterozygote advantage (perhaps the variance in pattern makes it more difficult for individuals to be spotted by a predator), return to the original parameters for population size, carrying capacity, and initial 'R' proportion, but decrease the Genotype Relative Fitness of the rr and RR individuals to 0.7 to indicate the advantage experienced by the heterozygote. Click the reset button to begin data collection. Allow the Allele Proportion vs Time 1 simulation to run for at least 100 generations, then sketch the graph: a. Proportion of "R" 0.5 b. Do any of the phenotypes go to zero? Why does this make sense?
