S1. Interpolated candidate gene distribution map for the
candidate SNP Etr_1806 on chromosome 04. Allele proportions are color
coded from low to high proportions of the A allele for Etr_1806 which
was associated with large adult body size in the Columbia River. Despite
relatively high numbers of large adults in the Klamath River, the
alternative allele G was found in higher frequencies in California,
which made association with body size inconsistent for this locus and
could indicate an unmeasured trait is the true target of selection.
