An allele has a frequency of 40% in a population of 2N=10 individuals. In the next generation, the allele was found to be at frequency 80% in the population. (a) Compute the probability of this change in allele frequency in a single generation if genetic drift is the only evolutionary force acting on the population. (b) Is such a large change in allele frequency in a single generation likely under a scenario where genetic drift is the only evolutionary force?
