Gene conservation between H. erato and H. melpomene contigs. Comparison of homologous genomic regions linked to the Cr color pattern gene in H. erato and Yb color pattern gene in H. melpomene. The top bar represents approximately 280 kb of sequence covering three BACs (clone AEHM-41C10 accession number CR974474, clone AEHM-7G12 accession number CT955980, and clone AEHM-11J7 accession number CU367882) for H. melpomene. The bottom bar represents approximately 350 kb of sequence covering three BACs (BBAM-12K4 accession number AC220074, BBAM-38A20 accession number AC193804, and BBAM-27D18 accession number AC199750). Genes showing a high similarity to know proteins in other arthropods are represented with black squares and arrows indicating orientation. The lines between the two sequences unite the homologous genes giving a visual representation of the overall synteny between the two species.
