Recent genetic and molecular data from Drosophila support the long-standing observations of morphology in suggesting that segmentation of the insect embryo proceeds in two phases. Organization of the cephalic segments uses a mechanism distinct from the familiar bierarchical cascade of segmentation genes that subdivides the trunk of the embryo.
来自果蝇的最新遗传和分子数据支持了长期以来的形态学观察结果，表明昆虫胚胎的分节过程分为两个阶段。头部节段的组织使用的机制不同于将胚胎躯干细分的常见的分层级联分节基因机制。
