Consider a population of cells where some cells are cooperative and some cells defect (are selfish). Fitness payoffs from interactions between any two cells are given by table below. Answer the two questions below. Cooperate Defect Fitness (C) (D) Cooperate (C) 9 4 Defect (D) 11 5 1) In a population where any two cells only interact once, is cooperation likely to evolve? Why or why not? 2) How will the likelihood that cooperation will evolve change if cells come together to form two types of groups: groups of all defectors (DDD) and groups of all cooperators (CCC), and why? In your answer, be sure to calculate and compare the fitness of cooperators and defectors in these groups.

1) In a population where any two cells only interact once, is cooperation likely to
evolve? Why or why not?
2) How will the likelihood that cooperation will evolve change if cells come together
to form two types of groups: groups of all defectors (DDD) and groups of all
cooperators (CCC), and why? In your answer, be sure to calculate and compare the
fitness of cooperators and defectors in these groups.
