hm1

• Allelic Composition: A^hvy/A^hvy
• Genetic Background: B6.C3-Bpifa2^a A^hvy

• ♀: phenotype observed in females
• ♂: phenotype observed in males
• N: normal phenotype

pigmentation

abnormal coat/hair pigmentation ( J:24247 )

• 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 dorsal coat color from yellow to darkened sooty yellow

integument

abnormal coat/hair pigmentation ( J:24247 )

• 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 dorsal coat color from yellow to darkened sooty yellow

ht2

• Allelic Composition: A^hvy/A
• Genetic Background: B6.C3-Bpifa2^a A^hvy

pigmentation

abnormal coat/hair pigmentation ( J:24247 )

• 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

darkened coat color ( J:24247 )

• this coat pigmentation is seen when yellow pigment (phaeomelanin) is minimal; the coat resembles non-agouti black

yellow coat color ( J:24247 )

• a creamy yellow coat color predominates but black striping or patches are seen on the back and/or belly

irregular coat pigmentation ( J:24247 )

• black striping or patches are frequently seen on the back and/or belly; the remainder of the coat is creamy yellow
