Sequence conservation and alignment diagram using Zpicture. Zebra finch BAC 157B03 and previously sequenced cosmid clone (rwcos3) from red-winged blackbird  were compared highlighting regions of sequence conservation. The Y axis in each panel represents the percent similarity. Exons (blue boxes), UTRs (yellow boxes) and intergenic regions are based on FGENESH predictions, and repeats (green boxes) are predicted by Zpicture  (using Repeatmasker). Regions of sequence similarity (brown boxes) not only include the Class IIB gene, but also the zinc finger-like sequences identified. Gene names are based on best BLAST hits. The ordering of genes is based on the zebra finch BAC assembly and is not necessarily the same in the red-winged blackbird.
