title: Polymorphism of yolk proteins in the interspecific hybrids of ducks.
abstract: 1. Polymorphism of lipid-free proteins of egg yolk by means of horizontal starch gel electrophoresis in Pekin, Muscovy ducks and their interspecific hybrids was studied. 2. In the interspecific hybrids of ducks the codominant type of heredity of beta livetin and transferrin were found.
