Degeneration patterns observed for lineages with at least 10 independent copies. (A) Mean size of copies in each lineage as a function of lineage divergence. The dotted line indicates the linear regression. (B) Ratio of nucleotides lost (by truncation or internal deletion) to nucleotides gained by insertion (log scale) as a function of lineage divergence. The dotted line corresponds to the median ratio. (C) Histogram of the deletion rate (number of nucleotides lost per substitution per lineage) distribution. (D) Deletion rates (internal deletion rate and truncation rate are dissociated) as a function of lineage divergence.
