Effective population size: 1,000 individuals per population. Statistics calculated across all individuals of simulated sample. Standard deviations included in parentheses.
^a Overall -- all individuals of two-population sample compared; Within -- individuals of same population compared; Between -- individuals of different populations compared; Cryptic -- random subset of 100 individuals compared.
^b Number of generations since two populations diverged.
^c Number of individuals sampled per population.
^d Average genetic distance for a set of pairs of individuals; standard deviation reflects variation in that average across individuals.
^e Standard deviation of individual CAPs, averaged across individuals.
^f Heterozygosity = 1 - ∑p_i where p_i is the population frequency of allele i. Averaged across loci.
^g Raggedness calculated according to Harpending [37].
