在果蝇中，许多好的单细胞标记方法都可以使用改变角质层结构或改变酶活性的突变。核酸与组织切片的原位杂交现在允许观察者跟踪胚胎中细胞群的运动。这些方法挑战了昆虫胚胎同色异构化的传统观点：似乎在外胚层和中胚层中，胚胎首先不是被分成节段，而是被分成区室和副节段。在外胚层中，副节段包括一个节段的后室和下一个节段的前室。在中胚层中，副节段可能不会再细分为区室。
In Drosophila , m any good methods of single cell marking are available using mutations that alter the structure of the cuticle or those that alter the activity of an enzyme. In situ hybridization of nucleic acids to tissue sections now allows the observer to follow movements of groups of cells in the embryo. These methods challenge the traditional picture of metamerization in the insect embryo: it seems that both in the ectoderm and the mesoderm the embryo is first divided not into segments but into compartments and parasegments. In the ectoderm a parasegment comprises a posterior compartment of one segment and the anterior compartment of the next. In the mesoderm the parasegments are probably not subdivided into compartments.
