The number of polymorphic loci (x 103) (A), and mean F ST across all loci (B), for different minor allele count thresholds ( n ) in the Constance (black) and Boot (gray) lake-stream stickleback system. This threshold specifies the minimum number of times the minor SNP allele at a locus had to occur in the pooled lake and stream sample for a polymorphic locus to remain in the data set.
