Mouse lines carrying:
A mutation (19 available); any a mutation (463 available)
Mc1rE-tob mutation (3 available); any Mc1r mutation (43 available)
♀ phenotype observed in females
♂ phenotype observed in males
N normal phenotype
pigmentation
abnormal coat/hair pigmentation ( J:22593 )
• Mc1rE-tob influences the expression of agouti
darkened coat color ( J:22593 )
• 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
