[Analysis of the frequency of spontaneous and induced autosomal recessive lethal mutations in the oogenesis of the radiosensitive mutant rad(2)201G1 of Drosophila melanogaster].

Abstract excerpt

The frequency of spontaneous and gamma-ray induced autosomal recessive lethals has been studied in chromosomes 2 and 3 at different stages of Drosophila melanogaster radiosensitive mutant rad (2) 201G1 oogenesis. The frequency of spontaneous lethals in radiosensitive mutant was higher by the order of magnitude as compared with wild-type flies (9.3 and 0.6%, respectively). Germ cells of radiosensitive mutant were...
