Genomic organization of eve genes in Capitella teleta. The two C. teleta eve genes are positioned 18.78 kbp apart on the same scaffold. Boxes indicate exons and lines between the boxes indicate introns. The sizes of intron 1 for both genes are indicated beneath the intron. Arrows indicate the direction of transcription. The five amino acid insertion 5' of the homeodomain in Ct-eve2 is marked. Gene names are indicated with scaffold coordinates in parentheses. The scaffold number and scaffold length is written at the left of the schematic. HD: homeodomain.
