pigmentation
abnormal hair follicle melanin granule distribution ( J:12724 )
• the white spotting appears to be due to a defect in the hair follicles which prevents pigment cells from entering the hair follicles or from developing there
belted ( J:283 )
• mice have a white band reaching across the back in the midtrunk region which sometimes joins a white belly spot of varying sizes
