Pip output of the comparison of tilapia HoxAα, striped bass HoxAα, pufferfish HoxAα, zebrafish HoxAα and Aβ, horn shark HoxA, human HoxA, and mouse HoxA clusters. The tilapia sequence has been used as reference sequence. Kilobase (kb) markings are based on the tilapia sequence. Blue background indicates coding regions, yellow indicates introns, red indicates conserved noncoding sequences (CNSs) previously described in literature, and the green background indicates heretofore undescribed CNSs. Horizontal arrows indicate the direction of transcription, tall black boxes showexons, short open boxes indicate a CpG/GpC ratio between 0.6 and 0.75, and short gray boxes indicate a CpG/GpC ratio over 0.75. Interspersed repeat elements are shown as triangles (e.g., in position 91 kb).
