[Chromosome aberrations induced by gamma radiation in the somatic cells of a radiosensitive mutant line of Drosophila melanogaster].
Chromosome aberrations induced by gamma-rays in ganglia cells of Drosophila melanogaster larvae have been studied. Two strains of Drosophila were used: radiosensitive mutant rad (2) 201G1 and normal strain. It has been shown that the frequency of cells with chromosome aberrations in radiosensitive larvae is much more than in normal larvae after gamma-irradiation. The ratio of chromosome and chromatid deletions number to the number of exchange type aberrations is the same for both strains. The kinetics of chromosome aberrations induced in rad-larvae is similar to the normal one. The conclusion has been made that the realization of rad (2) 201G1 mutation takes place on the cell level.
