Nondisjunction of the sex chromosomes and compound-second chromosomes was induced in Drosophila melanogaster by irradiation of immature oocytes and cold treatment of mature oocytes. These two treatments cause nondisjunction by different mechanisms. This results in a differential for stage sensitivity and the production of relatively different frequencies of the various exceptional progeny classes.
通过对未成熟卵母细胞进行辐射以及对成熟卵母细胞进行冷处理,在黑腹果蝇中诱导性染色体和复合第二染色体的不分离。这两种处理通过不同机制导致不分离。这导致了阶段敏感性的差异以及各种异常后代类型产生相对不同的频率。
