A permutation-based heuristic assigns testers to allelic classes according to estimates of AE combined across SNP assays. Combined estimates of AE for the 10 genes with at least two working SNP assays are shown, with strains ordered consistently across plots (labeled below CG11129 and CG11674). For each gene, bar plots are color coded according to the allelic classes identified by the heuristic. Error lines indicate 95% confidence intervals for relative AE. The table summarizes the data for all genes with at least one working assay: Assays, assays attempted (assays showing significant DAE); Combined P, the P-value for a significant difference among testers in the linear model fitted to all relevant assays AE estimates; n, number of observations per tester, as a harmonic mean; k, number of allelic classes identified by the permutation-testing heuristic; Membership, number of testers assigned to each allelic class.
