note.—Drosophila data set. Significant variables (P-value < 0.05) in italics. Model P-value is <2.2×1016, adjusted R2 is 0.6478. Model formula: relative model support ˜ number of sequences + total branch length + alignment length + length of coding sequence + GC content (mean) + GC content (SD) + total intron length + number of exons + maximum expression + mean expression + recombination rate.
