Consider the multilevel selection model shown below. Start with a population of 12 free-living cells (6 that cooperate and 6 that defect/are selfish). The cooperative cells are light pink and the selfish cells are purple. Groups of cells form at random and the cells in those groups reproduce. How many offspring each cell has (its fitness) is determined by its strategy and the strategies of the other cells in its group. The groups then break up, and the population is made up of 28 cells that cooperate and 14 cells that defect/are selfish. Answer the following questions. ୦୦୦ ୦୦୦ ୦୦ ୦୦୦୦ ୦୦୦୦ ୦୦୦୦୦ Cooperative Selfish Groups form at random Cells reproduce Groups break up 1) Did the frequency of cooperators in the population increase, decrease, or stay the same? 2) Is the increase, decrease, or lack of change in the frequency of cooperators (your answer to Q1) due mainly more to competition among cells within groups or competition between groups of cells? Select 2 correct answer(s) 00 Q1) The frequency of cooperators stayed the same Q1) The frequency of cooperators decreased Q1) The frequency of cooperators increased Q2) Competition among cells within groups Q2) Competition between groups of cells

Transcribed Image Text:Consider the multilevel selection model shown below. Start with a population of 12
free-living cells (6 that cooperate and 6 that defect/are selfish). The cooperative cells
are light pink and the selfish cells are purple.
Groups of cells form at random and the cells in those groups reproduce. How many
offspring each cell has (its fitness) is determined by its strategy and the strategies of
the other cells in its group. The groups then break up, and the population is made up
of 28 cells that cooperate and 14 cells that defect/are selfish. Answer the following
questions.

1) Did the frequency of cooperators in the population increase, decrease, or stay the
same?
2) Is the increase, decrease, or lack of change in the frequency of cooperators (your
answer to Q1) due mainly more to competition among cells within groups or
competition between groups of cells?
