Abstract

A decrease in delay of cleavage, when irradiated sperm fom Arbacia punctulata were allowed to “recover” inside eggs, occurred when cell division was interrupted by the removal of oxygen soon after fertilization. The recovery mechanisms in irradiated eggs of this species before and after fertilization have been compared and appear to differ.
