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.
已在野生型和重组缺陷型品系中研究了黑腹果蝇对紫外线的敏感性。通过测量经辐照的胚胎或幼虫发育成成年果蝇的比例来衡量存活率。鉴于该物种的雄性不参与减数分裂重组，因此重点研究了雄性和雌性的相对敏感性。结果表明，野生型雄性幼虫比雌性幼虫对紫外线辐射更敏感。然而，在一些重组缺陷型品系中，这种敏感性差异并不明显。此外，重组缺陷型品系Df(3)sbd105/T(2;E)Xa的幼胚对紫外线辐射异常敏感。
