Figure 3.

Frequency plots of the major allele for four outlier SNPs in sockeye salmon. SNPs correspond to (a) One_HpaI-99, (b) One_GPH-414, (c) One_MHC2-190, and (d) One_MHC2-251 genotyped across 31 Alaskan populations (see Table 1 for population codes). Squares represent lakes from the Alagnak subdrainage (Battle: black; Kukaklek: grey; Nonvianuk: empty), whereas circles represent lakes from the Kvichak subdrainage (Clark: black; Sixmile: grey; Iliamna: empty).
