pigmentation

darkened coat color ( J:13077 )

• at maturity flanks are flecked with yellow hairs and bellies may appear dark gray

• appearance is similar to homozygous non-agouti mice

abnormal skin pigmentation ( J:13077 )

hyperpigmentation ( J:13077 )

• skin is dark, ears and nipples are especially obvious
