Table 4.
Summary of the AFLP outlier analyses with Dfdist based on 614 loci. Six pair-wise comparisons were carried out between ecotypes, within localities. Average FST, 30% trimmed FST, and average FST of the simulations are shown. Sample sizes (N) of each ecotype within locality are also shown. “N outliers” represents the number of outliers (95th percentile) detected in each locality and “Overall” is the total number of distinct outlier loci combining the results from all the localities. “Shared outliers” are loci that were detected in two localities or regions. Expected values for shared outliers are simply based on the observed proportions in each separate analysis
