Probabilities of evolution of bold coloration for elapids (A) and dipsadids (B) and pitviper mimicry (C) by foraging type estimated by regression analysis. Odds ratios were calculated from the coefficient estimates of the largest marginal likelihood model (M2). The coloring corresponds with Fig. 2. A box, a bold line, and bars denote the interquartile range, median, and the range excluding outliers, respectively. The points below the first quartile – 1.5× interquartile range or above the third quartile + 1.5× interquartile range were regarded as outliers.
