Clusters of Nucleotide Substitutions and Insertion/Deletion Mutations Are Associated with Repeat Sequences
Figure 8
Human transcribed sequences accrue nucleotide substitutions in the sequence surrounding indels and their corresponding non-indel orthologous regions.
Recent duplications (<5% divergence) were aligned and non-duplicated orthologous regions from the Chimp genome were used as outgroups to allow identification of indel and non-indel haplotypes.
