 We'll start with what I call the "basic shades"​. These basic shades are controlled by two sets of genes: the Chocolate Gene, and the Dilution Gene. We'll start with what I call the "basic shades"​. These basic shades are controlled by two sets of genes: the Chocolate Gene, and the Dilution Gene.

-Like most furred animals, rabbits have two alleles for this gene, with symbols B and b respectively. When B is present (BB or Bb) the brown/black eumelanin is its normal, unlightened, ​colour: Black. But when a rabbit is bb the brown is lightened to Chocolate.+Like most furred animals, rabbits have two alleles for this gene, with symbols B and b respectively.

-In its recessive form, this gene has a diluting effect on both eumelanin and pheomelanin. When present in the homozygous recessive form (dd) it dilutes brown eumelanin to blue, chocolate to lilac, and red to cream.+In its recessive form, this gene has a diluting effect on both eumelanin and [[https://​en.wikipedia.org/​wiki/​Melanin#​Pheomelanin|pheomelanin]].
