Question

10) The graphs below show 4 simulations where a new mutation (the A1 allele) is favored by natural selection. No other evolutionary forces besides selection are acting. Which one of the following statements is true with respect to selection coefficients? a. The selection coefficient is larger for simulation #1 than for simulation #2 b. The selection coefficient is larger for simulation #3 than for simulation #2 c. Simulation #3 has the largest selection coefficient d. There is not enough information provided to determine relative magnitude of selection coefficients. relative magnitude of 1.0- #1 0.8- 06- Frequency of allele Al 0.4 0.2 20 40 60 80 100

Explanation / Answer

Answer

A. the selection coefficient is larger for simulation 1 than for simulation 2.

Selection coefficient larger if the steep of the curve is increase. So the number 1 shows the larger steep it has higher selection due to mutation.
