动物的颜色模式是由基因决定的，但其机制尚不清楚。提出了一种可以表现出无限多种模式的单一机制。提出了一个扩散驱动的反应扩散系统，该系统可能是动物皮毛斑纹预图案形成的原因。一个具体的实际底物抑制反应机理被认为是详细的。域的几何形状和规模，珠被的相关部分，在铺设的时间在所产生的结构模式中起着至关重要的作用。表现出有限的随机性的模式获得的选择的几何形状，并具体涉及到的斑点猫科动物，斑马和其他动物的毛色分布。
Color patterns in animals are genetically determined but the mechanism is unknown. A single mechanism which can exhibit an infinite variety of patterns is suggested. A reaction-diffusion system is proposed which can be diffusively driven unstable could be responsible for the laying down of the pre-pattern for animal coat markings. A specific practical substrate inhibition reaction mechanism is considered in detail. The geometry and scale of the domain, the relevant part of the integument, during the time of laying down plays a crucial role in the resulting structural patterns. Patterns exhibiting a limited randomness are obtained for a selection of geometries and are specifically related to the coat color distribution in the spotted felidae, zebra and other animals.
