title: Recombinant DNA studies on the structure, evolution, and developmental expression of structural gene families.
abstract: The structure of silkmoth chorion genes and their organization within the chromosomes are summarized. The multiple chorion genes are members of homologous gene families, and are physically linked. Their detailed structure and organization suggest mechanisms for their evolution and for the regulation of their expression.
