title: Genetic polymorphism of chicken 7S immunoglobulins.
abstract: A survey of 48 inbred lines derived from five sources in the United States and Europe revealed considerable genetic polymorphism of the CS-1 gene. A minimum of ten alleles were detected as unique combinations of CS-1 specificities. The relationship of some of the alleles would indicate that intracistronic recombination may have played a role in the production of some of the polymorphism.
