(A) Relationship between synonymous divergence in exons and evolutionary divergence in introns; R 2 = 0.511,P < 0.01. (B) Relationship between synonymous divergence in exons and evolutionary divergence in introns after removing CpG sites; R 2 = 0.137,P > 0.05. With the rightmost outlier excluded,R 2 = 0.06, P > 0.05.
