Two "selection" sub-populations (ris- and ris+), as well as two "temperature" ones (ric113 and ric149) were earlier developed from the control ric sub-population with interrupted vein of the fly wing. All five sub-populations were investigated for hybridization of MGE Dm-412 with drosophila polytene chromosomes in situ. The tree of similarity of MGE Dm-412 hybridization patterns was built by the methods of matrix clusterization. The sub-populations with the most resembling expressions of characters (ris- and ric113, ris+ and ric149) were found to be also most similar in patterns of MGE localization and their changes. Nonrandomness of these changes was shown, the similarity of patterns being demonstrated to be mainly the result of the changes. There is evidence that such effects cannot be accounted for by genetic drift and independent stochastic changes in MGE localization.
之前从具有果蝇翅脉中断的对照ric亚群中培育出了两个“选择”亚群（ris-和ris+）以及两个“温度”亚群（ric113和ric149）。对所有五个亚群进行了MGE Dm-412与果蝇多线染色体原位杂交的研究。采用矩阵聚类方法构建了MGE Dm-412杂交模式的相似性树。发现具有最相似性状表达的亚群（ris-和ric113，ris+和ric149）在MGE定位模式及其变化方面也最为相似。这些变化的非随机性得到了证明，模式的相似性被证明主要是这些变化的结果。有证据表明，这种效应不能用MGE定位中的遗传漂变和独立随机变化来解释。
