Sensitivity of wild type and recombination-deficient strains of Drosophila melanogaster to ultraviolet radiation.
The sensitivity of Drosophila melanogaster to ultraviolet light has been studied in wild type and recombination-deficient strains. Survival was measured as the proportion of irradiated embryos or larvae which developed to adult flies. In view of the fact that males of this species do not participate in meiotic recombination, emphasis was placed on the relative sensitivity of males and females. The results show that young wild type male larvae are more sensitive to UV radiation than are young female larvae. This difference in sensitivity, however, is not apparent in some recombination-deficient strains. In addition, young embryos of the recombination-deficient strain Df(3)sbd105/T(2;E)Xa are exceptionally sensitive to UV radiation.
