Effect of High Doses of γ-Radiation on the Development of Embryos of Cyclops insignis (Copepoda, Crustacea)

The results of the experiment have shown that the embryos of Cyclops insignis Claus, 1857 (Copepoda, Crustacea) exposed to γ-radiation at doses of 50 and 100 Gy at the 1-, 2-, and 4-cell stages develop to the 4–16-cell stage. It is assumed that high doses of radiation lead to an inactivation of the nuclear genome and the embryos develop to 8–16-cell stages based on cytoplasmic determinants.
