Choose all that apply. This graph shows the probability of fixation of a mutant
beneficial allele as a function of the selection coefficient, s, and the size of the
population, N.
In the White Sand desert, mutant lizards with an allele L that codes for light color are
at a fitness advantage; the estimated selection coefficient is s = +0.05.
According to the graph below, the probability that the L allele becomes fixed is
approximately (~plus or minus 0.1):
