Analysis of blood serum proteins electrophoretic spectra for perching and domestic ducks resulted in revealing interspecific differences of prealbumin and transferrin types showing incomplete identity of loci in analogous sites of some homologous chromosomes in the hybridizants. This confirms the genetic nature of sterility in this crossing combination hybrids whose blood serum proteins electrophoretic spectrum displays a complex hybrid phenotype.
