Ancestry of whitefish from Cliff Lake estimated using structure. (a) Ancestry estimates based on naïve clustering. Ancestry from the inferred dwarf and normal gene pools are shown in dark and light grey, respectively. (b) Likely ancestry of each individual, estimated using phenotypic information. White: full ancestry from observed ecotype. Light grey: one great grandparent with other ecotype. Grey: one grand parent with other ecotype. Dark grey: one parent with other ecotype. Black: both parents from other ecotype. See text for model details.
