the white spotting gene.Note: The cat shown top left has a mild form of radial hypoplasia
which has caused her deformed forelegs; she also has a slightly deformed skull.

cells migrate away from the neural crest, the dorsal area itself usually remains coloured in
low to medium grade spotting. The appearance of a white dorsal stripe is unusual and appears
to be hereditary.
