Assignment 5

Random genotypic and phenotypic changes in isolated populations can be overcome by migration. Both movement of organisms into a population and the migration of organisms out of a population can influence genotype frequencies. Migration can result in new alleles being introduced into a population. Conversely, when organisms migrate out of a population the frequency of certain alleles in the population can decline. Working within PopulationGeneticsLab and referring to the detailed instructions on Assignment 5, answer the questions below.
1 .       Run an experiment with a large amount of genetic drift occurring in 100 isolated populations by setting the number of stands to 100. To create migration among these populations, click on the Migration button and use the slider to change migration rate. Design and carry out experiments where there are different levels of migration occurring among the populations. For each of these experiments, carefully study what has happened to the populations by analyzing each category of results (genotype frequency, allele frequency, etc.). Does migration modify the effects of genetic drift? If so, how? Explain.
