pigmentation
• Background Sensitivity: amount and distribution of yellow pigment (phaeomelanin) relative to black or brown pigment (eumelanin) is variably increased or decreased compared with a wild-type agouti pattern resulting in a range of coat color from creamy yellow to black
• this coat pigmentation is seen when yellow pigment (phaeomelanin) is minimal; the coat resembles non-agouti black
• a creamy yellow coat color predominates but black striping or patches are seen on the back and/or belly
• black striping or patches are frequently seen on the back and/or belly; the remainder of the coat is creamy yellow
