Transcriptional correlations between con- vs heterospecifically-mated females of D. mojavensis and D. arizonae. Pairwise correlation coefficient matrix (Spearman’s ρ) of relative gene fold expression (log₂FC) was estimated only for genes with significant a) Differential expression (FDR < 0.05) and b) Alternative splicing (FDR < 0.01). Biologically meaningful correlations are highlighted for correlations: 45 min vs 6 h (yellow), con- vs heterospecific matings (green) and between species correlations (pink). Significant correlations (α < 0.05) are indicated with *
