6. a. Explain how individuals of aspecies are distributed when the species exhibits PopulationStructure. Include the following terms in your answer:
          Deme(=Subpopulation), Total Population.
     b. Inpopulation genetics what is meant by migrationbetween subpopulations of a species, and why will migration tend tokeep subpopulations similar genetically.
     c.Suppose you have 100 demes of a species, each with N=100, and eachwith allele frequencies f(A) = 0.5 and f(a) = 0.5. Draw two graphsrepresenting how genetic drift will affect allele frequencies inthe 100 populations; i. when no migration is occurring among demes,ii. when a moderate amount of migration is occurring among thedemes.
