Abundant indels in extensively edited genes. The COIII nucleotide sequence alignment using Sylvio X10, CL Brener and Esmeraldo is shown as an example. SNPs are indicated by 's' above the alignment and indels by 'i' below the alignment. In this particular case, indels outnumber SNPs 2:1. The distributions of SNPs and indels for COIII and other extensively edited genes are compiled in Table 4.
