Kjetill S. Jakobsen, Sissel Jentoft and colleagues assemble partial draft genomes and analyze sequences from 66 teleost fish species to determine major histocompatibility complex (MHC) class I and class II gene status. They find that MHC II is absent from the Gadiformes lineage, while MHC I gene expansions have occurred multiple times.
