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 mu filter or autoclaved did not increase membrane formation over that of the controls. Fertile membranes behaved like parthenogenetic membranes.
单性生殖卵的发育在一个黑康沃尔鸡种群中通过膜形成或胚胎形成来体现。双黄卵在零个、一个或两个卵黄中形成膜。与来自同一母鸡的单黄卵的发生率相比，具有两个膜的双黄卵的发生率高于预期。通过注射生理盐水、林格氏液或研磨的粗膜，膜的形成比对照组增加。通过3微米过滤器过滤或高压灭菌的卵黄和膜与对照组相比并没有增加膜的形成。可育膜的表现与单性生殖膜相似。
