An analysis was carried out of the peculiarities of interlocation of primary ovarian trophocyte polytene chromosomes of Drosophila sechellia in comparison with seven earlier-described species of the melanogaster subgroup. Based on the data from this analysis and earlier-known results of reconstruction of the reconstruction of the subgroup phylogeny, the following trend in the evolution of the architectonics of trophocyte chromosomes is suggested: from a local tight chromocenter (D. orena), to a diffuse chromocenter (D. erecta, D. simulans, D. sechellia), to its complete disappearance (D. yacuba, D. mauritiana), and to tight binding of chromosomes to the nuclear membrane (D. teissieri, D. melanogaster).
对塞舌尔果蝇初级卵巢滋养细胞多线染色体的位置特点进行了分析，并与黑腹果蝇亚组中先前描述的七个物种进行了比较。基于该分析数据以及亚组系统发育重建的早期已知结果，提出了滋养细胞染色体结构演化的以下趋势：从局部紧密染色中心（奥伦那果蝇），到弥散染色中心（ erecta果蝇、拟暗果蝇、塞舌尔果蝇），再到其完全消失（雅库巴果蝇、毛里求斯果蝇），最后到染色体与核膜紧密结合（泰西埃果蝇、黑腹果蝇）。
