N normal phenotype
pigmentation
• Mc1rE-tob influences the expression of agouti
• the color is difficult to distinguish from non-agouti black before 8 weeks of age when agouti hairs appear on the flanks; the back remains darkened
• Mc1rE-tob/Mc1re mice that are also homozygous non-agouti are black because Mc1rE-tob only affects the expression of agouti

integument
• Mc1rE-tob influences the expression of agouti
• the color is difficult to distinguish from non-agouti black before 8 weeks of age when agouti hairs appear on the flanks; the back remains darkened
• Mc1rE-tob/Mc1re mice that are also homozygous non-agouti are black because Mc1rE-tob only affects the expression of agouti
