  1. Abbreviations: H, heptacosene; HD, heptacosadiene; MtnA, metallothionein A; P, pentacosene; PD, pentacosadiene and QTL, quantitative trait loci.
  2. a See Table 1 for compound abbreviations. Only compounds showing epistatic interactions are presented.
  3. b The nearest marker to the likelihood peak of each QTL was used in the analysis (see text).
  4. c Epistatic interactions between QTL were detected using generalized linear models with loci as covariates and all first order interactions for allelic data at the nearest marker to the QTL. The appropriate Bonferroni significance level is 0.008.
