A dysgammaglobulinaemic line of chickens homozygous at the major histocompatibility complex has been established. In these chickens the IgG levels are decreased 10 to 100 times and IgM levels are increased 2 to 10 times when compared to those of normal birds. Dysgammaglobulinaemia is genetically determined. No linkage with the major histocompatibility complex of the chicken has been found.
