Fig. 2.

Chromosome size variation and local genomic expansions. The results are shown for the reference-guided assemblies mapped to the closest reference (either H. melpomene or H. erato demophoon; see supplementary table 2, Supplementary Material online). (a) Chromosome sizes in proportion to the genome size across the different species for the reference-guided assemblies mapped to the H. melpomene reference genome. Chromosome relative sizes are generally similar across species, with the exception of H. hecale, H. elevatus, and H. pardalinus, particularly chromosome 9. (b) Genome to genome alignment showing the repeat region on chromosome 9 (highlighted by the gray rectangles) in the species trio: H. hecale, H. elevatus and H. pardalinus.
