The experimental results show that at doses of 20 Gy and 100 Gy, the development of Lilljeborg, 1901 (Copepoda, Cyclopoida) embryos ceases at the 16-cell stage, without affecting the course of chromatin diminution. A dose of 200 Gy terminated the process of chromatin diminution in some of the embryos. These results support the hypothesis that cytoplasmic factors in the egg play an important role in the process of chromatin diminution.
实验结果表明,在20戈瑞和100戈瑞的剂量下,1901年的利尔耶博里格(桡足亚纲,剑水蚤目)胚胎发育在16细胞阶段停止,而不影响染色质消减过程。200戈瑞的剂量使一些胚胎的染色质消减过程终止。这些结果支持了卵中的细胞质因子在染色质消减过程中起重要作用这一假说。
