Figure 4.

Principal Components Analysis using RSTA array log ratio data show a signal of population differentiation in a high gene flow species. Symbols represent individuals from Oregon (blue circles) and San Diego (red triangles). (a) All polymorphic coding loci, 6,859; (b) polymorphic coding loci excluding top FST loci, 6,555; and (c) top FST polymorphic coding loci, 304. Patterns were similar for other tiles in non-coding regions.
