Relative expression impacts of chromosomal inversions. Log fold-change in inversion heterozygotes and homozygotes relative to standard arrangement homozygotes for In(2L)t (Left) and In(3R)K (Right) with natural inversions (Top) and synthetic inversions (Bottom). Expression differences that are significant at the q < 0.2 level are shown as red (additive), blue (overdominant), and green (underdominant).
