In mice, spotted coat color is due to a recessive gene s and solid coat color to its dominant allele S. Colored mice possess a dominant allele C whereas albinos are homozygous recessive cc. Black is produced by a dominant allele B and brown by its recessive allele b. The cc genotype is epistatic to both the B and S loci.
