[The peculiarities of the radiation mutagenesis of Cyclops kolensis and Cyclops insignis (Crustacea, Copepoda)].
The frequency of the chromosomes aberrations (FA) of Cyclops kolensis before chromatin diminution (CD), which were inducted by gamma-irradiation in 50 times exceeds the FA of Cyclops kolensis after CD, during the CD, reducing the genome of C. kolensis in 15 times. During the embryogenesis the FA of Cyclops insignis doesn't change. The obtained results show us a low level of the spontaneous mutagenesis of C. kolensis and C. insignis embrios. The FA of Cyclops kolensis is correlated with the doses 1, 2, 3, 5 Gy gamma-irradiation. The similarity of the CD mechanism and of the mechanism of the chromosome aberrations is supposed.
