ANOVA = analysis of variance; SMM = stepwise mutation model; TPM = two-phase model.
Statistically significant differences by collection, over all 14 loci in AP, A frequency ≥ 0.50, and A frequency < 0.05 (repeated measures ANOVA, P = 0.012, P = 0.000821, and P = 9.23 × 10−6, respectively).
Statistically significant post hoc, Bonferroni-corrected pairwise t tests.
TPM settings: proportion of SMM in TPM = 0; variance of geometric distribution for TPM = 36 [per Bottleneck software website (http://www1.montpellier.inra.fr/CBGP/software/Bottleneck/pub.html)].
No statistically significant differences by collection, over all 14 loci in A, nor FIS (ANOVA, P = 0.0669, and P = 0.9, respectively).
