Alignment of zebrafish BACs to the linkage group 7 of the ZV4 whole genome shotgun assembly. Approximately 600 Kb of the zonadhesin locus from the ZV4 assembly is shown on the x-axis. Alignments of this region to zebrafish BACs, the puffer fish (fugu) zan locus (Scaffold 860) and human 7q22 were performed using MultiPipMaker. Regions of high conservation consisting of gap-free alignments of at least 100 bp and 70 percent nucleotide sequence identity are shown in red and other locally aligned regions are shown in green. RepeatMasker  was used to mask zebrafish repeats before the alignments were made.
