显色素抑制基因 I（银化）带宽基因Wb细纹虎斑
在银化猫咪中，I是存在的；在金化猫咪中，没有I。
带宽基因Wb完全独立于抑制基因 I ，但它本身是多基因遗传，只是用简化为Wb去描述。
不带I的细纹虎斑，Wb会抑制毛发的根部色素合成：这样就在皮肤和色素正常段毛发之间，生成了一个浅黄色的区段。
通过选择育种，这一段浅黄色区段的宽度被大大增加。我们用Wb、Wb+和Wb++来描述具有正常、中等和极高宽带宽度的猫咪。
Shaded and tipped (shell/chinchilla) are due to the dominant Inhibitor gene (silver) + presence of Wide Band + the Ticked Tabby pattern. In silver cats the dominant Inhibitor is present. In golden cats, the dominant Inhibitor is absent. Wide Band is independent from the Inhibitor gene and though "Wb" is treated as a single dominant gene for simplicity, it appears to act as polygenes with an additive effect. In ticked tabby cats without silver, Wide Band restricts the pigment to the end of the hair leaving a pale golden band between the skin and the pigment. Through selective breeding, this effect has been maximised. The variability of the wide band suggests we should talk about Wb, Wb+ and Wb++ to describe cats with normal, intermediate and greater degrees of Wide Banding.
