Polymorphism in Multilocus Host-Parasite Coevolutionary Interactions

From: Genetics | Date: November 1, 2007| Author: Brown, James K M; © lien; Tellier, Aurà | Copyright information

ABSTRACT

Numerous loci in host organisms are involved in parasite recognition, such as major histocompatibility complex (MHC) genes in vertebrates or genes involved in gene-for-gene (GFG) relationships in plants. Diversity is commonly observed at such loci and at corresponding loci encoding antigenic molecules in parasites. Multilocus theoretical models of host-parasite coevolution predict that polymorphism is more likely than in single-locus interactions because recurrent coevolutiona...
