NOTE.—Repeats were identified by Blasting each genome to itself (see Materials and Methods) and considering all hits with a Blast expect value ≤1. Repeats are defined by their begin and end coordinates in the genome. In tallying the total number of repeats, those with identical begin and end coordinates are counted only once. Percent coverage is the percentage of nucleotide positions in the genome occupied by repeats of given length category (column 1), calculated without respect to repeats in other length categories. Whereas the number of repeats is additive among rows, the coverage values are not because repeats can (and do) overlap.
