The object of this study was the distribution of macrochaetae and microchaetae on the scutellum of Drosophila melanogaster in wild-type individuals and in three mutant genotypes: h/h, al/al and al; h/al; h. The mutation h (hairy) causes the appearance on the scutellum of extra microchaetae with a definite distribution pattern. The mutation al (aristaless) changes the size and the shape of scutellum and causes the shift of the posterior scutellar bristles. It is shown by the study of double homozygotes al; h/al; h, that this bristle can be shifted into the region occupied by one of microchaetae. The results obtained are considered in the light of the prepattern hypothesis. An assumption is made about the possible three-component constitution of the system of pattern formation.
本研究的对象是野生型个体以及三种突变基因型（h/h、al/al和al; h/al; h）的黑腹果蝇小盾片上大刚毛和小刚毛的分布情况。突变h（多毛）会导致小盾片上出现具有特定分布模式的额外小刚毛。突变al（无触角）会改变小盾片的大小和形状，并导致小盾片后刚毛的移位。通过对双纯合子al; h/al; h的研究表明，这种刚毛可以移位到其中一根小刚毛所占据的区域。根据预模式假说对所得结果进行了分析。并对模式形成系统可能的三组分构成做了假设。
