• Background Sensitivity: whereas mice heterozygous for wad on a nonagouti brown (a/a Tyrp1b/Tyrp1b) background exhibit obvious coat color dilution, on the agouti (A/A) background of C3H/W heterozygosity for this mutation has no apparent effect

• Background Sensitivity: whereas heterozygosity for this mutation has no apparent effect on the agouti (A/A) background of C3H/W, on this nonagouti brown background, the coat color of mice heterozygous for wad is obviously diluted--the shade of milk chocolate versus the dark brown of wild-type animals--with occasional, interspersed darker hairs
