Genomic organization of the rainbow trout and zebrafish IgH loci. Two major sequence contigs (107 and 14 kbp) resulted for the trout IgH.1 locus, which have been merged into a single contig within the δ gene. The three trout VH genes are members of the VH2, -8, and -5 families, respectively (18). The zebrafish locus (≈75 kbp) is based on ensembl supercontigs ctg14038, ctg1404, and ctg14057 and BAC sequences BX649502 and BX510335. ψ, pseudogenes; R, repetitive regions; →, transcriptional orientation.
