ANALYSIS OF DOMINANT AND RECESSIVE SEX-LI NKED LETHAL MUTATIONS INDUCED BY LOW RADIATION-DOSES IN GENETICALLY DIFFERENT STRAINS OF DROSOPHILA-MELANOGASTER W AND MS

Frequencies of induced recessive sex-linked lethal mutations (RSLLM) a nd dominant lethal mutations (DLM) were analyzed in genetically differ ent Drosophila melanogaster strains w and ms after their exposure to r adiation on radioactive soil in laboratory conditions. The RSLLM test applied to males after their 14-day radiation exposure yielded controv ersial results. An analysis of induced and spontaneous DLM demonstrate d an increase in the frequency of early embryonic lethal mutations in the experiment (radiation exposure) in comparison with the control (sp ontaneous mutation rate) in both strains examined.
