In developmental biology, pattern formation refers to the generation of complex organizations of cell fates in space and time. Pattern formation is controlled by genes. The role of genes in pattern formation is an aspect of morphogenesis, the creation of diverse anatomies from similar genes, now being explored in the science of evolutionary developmental biology or evo-devo. The mechanisms involved are well seen in the anterior-posterior patterning of embryos from the model organism Drosophila melanogaster (a fruit fly), one of the first organisms to have its morphogenesis studied and in the eyespots of butterflies, whose development is a variant of the standard (fruit fly) mechanism.

在发育生物学，模式形成指的是细胞在空间和时间中命运的复杂组织的产生。模式的形成是由基因控制的。基因在模式形成中的作用是形态发生的一个方面，即从相似的基因中创造不同的解剖结构，目前正在演化发育生物学或演化发育生物学中探索。其中涉及的机制可以从模式生物黑腹果蝇(一种果蝇)的胚胎前后图案和蝴蝶的眼点中清楚地看到，后者的发育是标准(果蝇)机制的变体。

Biological patterns such as animal markings, the segmentation of animals, and phyllotaxis are formed in different ways.

In developmental biology, pattern formation describes the mechanism by which initially equivalent cells in a developing tissue in an embryo assume complex forms and functions. Embryogenesis, such as of the fruit fly Drosophila, involves coordinated control of cell fates. Pattern formation is genetically controlled, and often involves each cell in a field sensing and responding to its position along a morphogen gradient, followed by short distance cell-to-cell communication through cell signaling pathways to refine the initial pattern. In this context, a field of cells is the group of cells whose fates are affected by responding to the same set positional information cues. This conceptual model was first described as the French flag model in the 1960s. More generally, the morphology of organisms is patterned by the mechanisms of evolutionary developmental biology, such as changing the timing and positioning of specific developmental events in the embryo.
