  1. The impact of indels on X-rich MRI regions and on X-average regions, where X is for GC-, GT-, or GA-rich or poor. For each particular region we give the total length of examined regions in mega-bases, the percentage composition or content of X, the number of changes in X due to insertions and deletions (ΔX = N ins (X) - N del (X)), and the net change in X composition due to both indels and substitutions.
