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
