*For the Tribolium genome, average density = number of repeats/151 Mb; for the Drosophila genome, average density = number of repeats/144 Mb. †The size of the Drosophila genome was calculated by summing the euchromatin (124,006,872 bp) and heterochromatin (19,948,491 bp) not including sequence gaps.
