The salmonid class I MHC: limited diversity in a primitive teleost
Summary: Three MHC class I genes have been characterized in salmonids: A, B, and UA. Levels of polymorphism vary among the genes, but they all share one common feature: a lack of sequence diversity. Although individual species can carry over 3.0 alleles at a given locus (A), intraspecific diversity...

Levels of polymorphism vary among the genes, but they all share one common feature: a lack of sequence diversity.
