In Drosophila melanogaster structural genes are located close to moderately reiterated sequences. One of the clones obtained contains the DNA related to intercalary heterochromatin of D. melanogaster. These are individual differences in the distribution of genetic material in polytenic chromosomes of different stocks of D. melanogaster. The techniques that allow isolation of DNA fragments containing structural genes at the beginning, in the middle, or the end of the coding strand have been elaborated.
在黑腹果蝇中，结构基因位于中度重复序列附近。获得的一个克隆含有与黑腹果蝇居间异染色质相关的DNA。在不同黑腹果蝇品系的多线染色体中，遗传物质的分布存在个体差异。已经开发出了能够分离包含编码链起始、中间或末端结构基因的DNA片段的技术。
