Figure 4.

Diagrammatic representation of the chromosomal location of the spiggin multi-gene family, its homologs, and Muc19. Spiggin (threespine stickleback), spiggin homologs (torafugu, spotted green pufferfish, medaka, and zebrafish), and Muc19 (mouse and human) are indicated in red, and other genes are indicated in other colors. Orthologous genes are connected by dotted lines. Spiggin, its homologs, and Muc19 are connected by solid lines.
