Consistency of sequence divergence with divergence in expression context for expanded orthologous groups. Consistency (positive correlation) or inconsistency (negative correlation) of sequence divergence with divergence in expression context for all expanded orthologous groups (X-X orthologs, except 1–2 orthologs). Plotted frequencies are the number of X-X orthologous groups with a positive and negative correlation. P is the probability to find at least this number of positively correlated observations by chance (binomial distribution).
