aEnrichment (based on DNA-array data) of gene classes in the group of genes with variation linked to isolation site (3,742 genes) and the group of polymorphic genes that were not linked to isolation site (3,965 genes).

bSignificance in –log10(p).

cGene classes with group sizes ≥ 6, overlap ≥ 3 genes, and significance ≥ 2.5.
