The Graphs Below Show the Results of Simulations of the Effect

question 5

Not Answered

The graphs below show the results of simulations of the effect of selection on deleterious alleles. Population size is infinite in both simulations, and the starting frequency and the strength of selection are the same. The graphs below show the results of simulations of the effect of selection on deleterious alleles. Population size is infinite in both simulations, and the starting frequency and the strength of selection are the same.   (a) Based on the shape of the curves, why do the results of the simulations differ? Explain your answer. (b) The allele in the second simulation is not eliminated entirely from the population. Would this change if the population was finite in size? Why or why not? (a) Based on the shape of the curves, why do the results of the simulations differ? Explain your answer.
