FIG. 6.

Chromosomal location of carp sequences with multiple blast hits in the zebrafish genome. (a) Plot of the number of BLASTN hits per zebrafish exons against the carp genome (y axis) versus the zebrafish genome location (x axis) shows an even distribution of duplicated exons, with the exception of several genomic regions which show extensive apparent multiplication in the carp genome. The plot was made using the software program UCSC genomegraphs. (b) Detailed view of zebrafish chromosome 4. Exons with more than 15 BLASTN hits are indicated in black. The plot was made using a custom R script of the number of blast hits versus the chromosome location.
