Pairwise correlations and covariance analyses with population and pigment synthesis fitted as cofactors.

Pairwise (Pearson) correlations of trait pairs, and covariance analyses (linear regression) with replicate selection line, and replicate selection line with colony colour fitted as covariates. The first trait of the trait pairs is the dependent variable in the regression analyses. Significant values (>0.05) are highlighted.1Effect of replicate selection line, i.e. population identity.2Effect of colony colour, i.e. prodigiosin synthesis.
