Fig. 4From: The metabolome as a link in the genotype-phenotype map for peroxide resistance in the fruit fly, Drosophila melanogasterProjections of Metabolomic Principal Components The first and second principal components of the negative mode data labeled to indicate resistant and sensitive genotypes, as well as the effect of treatment (control vs. H2O2). Trait and treatment groups are indicated by colored points and ellipses (50% CI). The percentage of the variance explained by each PC is shown in parenthesesBack to article page
