From: Evolution of duplicated IgH loci in Atlantic salmon, Salmo salar
Phylogenetic tree based on nucleotide sequences of Atlantic salmon and rainbow trout V H genes. The tree was constructed from complete exon 2 sequences (without the RSS). These Atlantic salmon VH genes could be grouped into 18 families (Fam 01 - 18), based on >75% nucleotide similarity. Examples from thirteen VH families of rainbow trout [40, 41] are shown in red letters.
