Let us imagine that we sequence the genomes of several pilot whales and estimate the nucleotide diversity at neutral autosomal loci to be 0.02 per site. Let us imagine that we have also measured the mutation rate to be 5 x 10⁻⁸ mutations per site per generation. What is the effective population size (Ne) of the pilot whales?

a. 250,000
b. 200,000
c. 100,000
d. 50,000
