Results of an F _ST modeling approach to detect loci under selection. Empirical F_ST values have been plotted against heterozygosity for each pairing of DLC-sensitive and DLC-tolerant sites (A) and for the pooled DLC-sensitive/-tolerant comparison (B). Gray lines represent the 95^th percentile and black, dotted lines represent the 99^th percentile. Red data points indicate outlier SNPs with respect to the F_ST null distribution.
