Father and daughter 'wear' the same 'mask'

My reading of the genetics behind this father and daughter cat looking as they do (very cute and very rare) is that they have the white spotting gene or piebald gene in their genetic makeup and it has caused this highly unusual Zorro mask to develop. I guess it is just by chance that the white spotting gene had this effect upon the way the pattern developed. I don't think that there is any special genetic mutation going on here.

The white spotting gene normally simply results in a standard bicolour cat. These two are bicolour cats but the markings are remarkable. Normally the markings are just black-and-white blobs or a white background with markings being created by darker coloured fur. An example of a bicolour cat is the Harlequin. I have a page on bicolor cats. Please click on the link below.
