  • a Letters in parentheses represent positions in Figure 2.

  • b C, Cvi genotype; L, Ler genotype.

  • c Proportion of phenotypic variation additively explained by epistatic interaction compared with the single-gene effect of the first marker [(gene effect of the first marker conditioned by the second marker) − (single-gene effect of the first marker)].
