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.
当辐照的扇贝多精卵被允许在卵子内“恢复”时，其卵裂延迟减少，如果在受精后不久去除氧气，细胞分裂就会被打断。该物种辐照卵在受精前后的恢复机制已被比较，似乎有所不同。
