A total of 31 genomic regions contained the top 0.1% of SNP ranked using global F _ST (47 SNP). The top 5% of SNP were used to define the boundaries of each region using a stepping approach (see Materials and Methods). The number of genes and number of top SNP (0.1%) are given for each region along with candidates for selection.
