Figure 5. Temporal distributions of candidate SNPs for characterizing phenotypes of the adult Pacific lamprey migration at Willamette Falls.The timing of AA versus CC genotypes at Etr_464 demonstrates relative migration of the “mature” and “premature” ecotype for both a)2014 and b)2015 runs. The line charts (a – b) indicate the relative abundance of genotypes at Etr_464 across statistical weeks and the pies indicate the relative proportions of those genotypes for first and second halves of the run. The migration timing of the AA and AC genotypes at Etr_5713 of fish that were phenotypically small-bodied “ShortAA/AC” versus phenotypically large-bodied “LongAA/AC” was relatively early and late, respectively, for both c)2014 and d)2015 runs. Late stages of maturation causes body size shrinkage (Clemenset al . 2009) and so even genotypes associated with large and intermediate body size (i.e. genotypes AA and AC at Etr_5317) can exhibit relatively short body lengths in the lower 50% distribution of length (“ShortAA/AC”) when they mature. The line charts (c – d) indicate relative abundance of the “Short” and “Long” phenotypes of the Etr_5317 genotypes and the pies indicate the relative proportions of those phenotype-genotype groups for the first and second halves of the run
