Primary chromosome damages as well as the frequency of spontaneous and X-rays induced chromosome aberrations in Drosophila melanogaster males and females are studied. It is found using cytofluorimetric method that primary chromosome damages in ganglia cells of females and males are the same. In these cells as well as in cells of imaginal discs the frequency of induced chromosome aberrations, except gaps, is considerably higher for females. Ganglia cells of females and males of Drosophila are found not to differ from each other in their proliferation activity. The frequency of morphoses for both sexes is also the same. The assumption is made concerning the role of the non-identical repair in the increased mutability of female somatic cells, which is more intensive in this sex, as well as concerning more intensive identical repair in imaginal discs of females.
对黑腹果蝇雌雄个体的原发性染色体损伤以及自发和X射线诱导的染色体畸变频率进行了研究。使用细胞荧光分析法发现，雌雄个体神经节细胞中的原发性染色体损伤是相同的。在这些细胞以及成虫盘细胞中，除了裂隙外，雌性诱导染色体畸变的频率明显更高。发现果蝇雌雄个体的神经节细胞在增殖活性上没有差异。两性的形态变化频率也相同。提出了关于非同一性修复在雌性体细胞更高变异性中所起作用的假设，这种变异性在雌性中更为强烈，同时也提出了关于雌性成虫盘中更强烈的同一性修复的假设。
