One of the first steps in segmentation of the Drosophila embryo seems to be not the formation of segments, but instead the definition of 14 domains, each of which encroaches into adjacent segments. We call these domains parasegments and discuss their developmental significance.
果蝇胚胎分割的最初步骤之一似乎并非体节的形成,而是14个区域的界定,每个区域都侵入相邻的体节。我们将这些区域称为副体节,并讨论它们的发育意义。
