Abstract

Development of parthenogenetic eggs is expressed in a Dark Cornish stock by either membrane or embryo formation. Double‐yolked eggs have membranes developing in zero, one, or two yolks. The incidence of double‐yolked eggs with two membranes was higher than expected when compared with the incidence of single‐yolked eggs from the same hens. Membrane formation was increased over that of the controls by injecting saline, Ringer's solution, or ground crude membranes. Yolk and membranes filtered through a 3 μ filter or autoclaved did not increase membrane formation over that of the controls. Fertile membranes behaved like parthenogenetic membranes.
