Some very interesting results to illustrate the mechanism of cytoplasmic control of primary differentiation were obtained by Davidson and co-workers (1965). They studied the early embryo-genesis of the mollusk Ilyanassa obsoleta an organism which was previously shown to offer exceptional opportunities for investigations of this type. During oogenesis the cytoplasm of the oocyte...
