Low MHC variation in the endangered Galápagos penguin (Spheniscus mendiculus).

Immunogenetics - 1 Jul 2007

Bollmer Jennifer L, Vargas F Hernán, Parker Patricia G

Abstract excerpt

The major histocompatibility complex (MHC) is one of the most polymorphic regions of the genome, likely due to balancing selection acting to maintain alleles over time. Lack of MHC variability has been attributed to factors such as genetic drift in small populations and relaxed selection pressure. The Galápagos penguin (Spheniscus mendiculus), endemic to the Galápagos Islands, is the only penguin that occurs on...
