HoXC-6 基因在 鸟和蛇 胚胎中 的表达 模式 Hox genes determine the form, number, and evolution of repeating parts, such as the number and type of vertebrae in animals with backbones In the developing chick(left), the Hoxc-6 gene controls the pattern of the seven thoracic vertebrae(highlighted in purple), all of which develop ribs In the garter snake(right), the region controlled by the Hoxc-6 gene(purple) is expanded dramaticallyforward to the head and rearward to the cloaca
