A Macaque's-Eye View of Human Insertions and Deletions: Differences in Mechanisms

(A) Insertion versus deletion rates. (B) Indel rates versus divergence. (C) Indel rates versus GC content. In all three instances, the quadratic fits (p < 10−15 for (A–C)) explained the data better than linear fits. Empty circles, chromosome X windows; filled circles, autosomal windows; purple circles, windows skewed toward insertions; green circles, windows skewed toward deletions; pink circles, windows skewed toward indels; blue circles, windows skewed toward nucleotide substitutions.
