  3. Chinook microsatellite standardization objectives • Develop a standardized coast-wide DNA baseline that will resolve lineages and stocks within the region for which the CTC is responsible • Facilitate future expansion of the DNA baseline and addition of novel genetic markers through exchange of DNA samples • Develop a data base application to support the dissemination and growth of the baseline

  5. 2-Year GAPS study design • Year 1: Standardization • Select a common set of markers • Standardize allele designations • Select baseline populations for year 2 • Year 2: Baseline development • Verification via blind samples • Sample exchange • Data collection and storage • Power analysis

  6. Samples 500-sample survey set (10 individuals from each of 47 populations, range-wide) 96-sample reference set (8 individuals from each of 12 regions) 96-sample blind tests (diverse mixture samples) 15,000-sample baseline set (144 individuals from each of 105 populations ) *Current focus on microsatellites, future interest in SNPs “Marker (=locus) sets” and “Sample sets” Markers* • 62 sponsored loci • 25 candidate loci • 13 finalists for baseline construction

  7. Blind test of standardization

  8. Partially corrected concordance

  9. Example blind test errors from one of the laboratories No. Source of Error 6 Faint or large allele dropout - DNA quality 4 Conversion typo 4 Sample order? 1 Artifact?

  10. Current Chinook Coast-wide baseline • ~16,000 individuals • 110 populations (>230 samples) • 37 regions, Gulf of AK to Central Valley CA • Preliminary analyses complete • Descriptive pop gen • Power analysis

  11. Standardized GAPS loci • Alleles per locus: 37.6 (7 – 71) • Heterozygosity: 0.85 (0.52 – 0.95) • FST: 0.071 (0.03 – 0.22)

  16. Results summary • Concordant genotyping among laboratories • High heterozygosity (~500 alleles) • No obvious HW departures or linkage disequilibrium • High concordance with previous genetic studies • Powerful mixture analyses, both proportional estimates and individual assignment

  17. Ahead… • Expand baseline • Comprehensive power analysis • Safe and secure repository for data • QC and certification of new labs
