N normal phenotype
pigmentation
yellow coat color ( J:15080 )
• pale yellow in color
variegated coat color ( J:13812 , J:15080 )
• mutation causes fluoresence of the coat by long-wave UV light; no fluorescent areas where there is normal albino hair (J:13812)
(J:15080)
abnormal skin pigmentation ( J:13812 )
• mosaic of yellow is seen in the skin even in areas that have albino hair suggesting the mutation is not related to pigment cell activity
