The C locus is one of the most complex color loci. A rabbit can be either C_, c(chd)_, c(chl)_, c(ch)_, or cc.
C_ is normal. It can be CC, Cc(chd), Cc(chl), Cc(ch), or Cc. It is the most dominant on the C locus. Varieties recognized in Holland Lops that are C_ at the C locus are:
~All varieties apart from REW, Pointed White, Chinchilla, Squirrel, Chocolate Chinchilla, Silver-Tipped Steel, Sable Point, Smoke Pearl, Seal, and Siamese Sable.
c(chd) is dark chinchilla. Chin can be either c(chd)c(chd), c(chd)c(chl), c(chd)c(h) or c(chd)c. The c(chd) allele is responsible for chinchilla color. It is recessive to C, but dominant to c(chl), c(h), and c. Rabbits that do not carry the c(chl) allele typically show the best Chinchilla coloring, as the c(chl) gene can muddy the color. Varieties recognized in Holland Lops that are c(chd)_ at the C locus are:
~Chinchilla
~Squirrel
~Chocolate Chinchilla
~Frosty
~Black/Blue/Chocolate/Lilac Silver-Tipped Steel
c(chl) is the sable gene. Sable can be either c(chl)c(chl), c(chl)c(ch), or c(chl)c. The c(chl) allele is responsible for shading of sable-based varieties (not tortoise). It is recessive to C and c(chd), but dominant to c(h) and c. Varieties recognized in Holland Lops that are c(chl)_ at the C locus are:
~Sable Point
~Seal (must be homozygous)
~Smoke Pearl
~Siamese Sable
c(ch) is the pointed white, aka Himalayan gene. Himalayan can be either c(ch)c(ch) or c(ch)c. The c(ch) allele is responsible for dark points on a white background. It is recessive to C, c(chd), and c(chl), but dominant to c. Varieties recognized in Holland Lops that are c(ch)_ at the C locus are:
~Black/Blue/Chocolate/Lilac Pointed White
c is Ruby-Eyed White aka REW. REW is albino. REW can ONLY be cc. It is recessive to all other C locus alleles, but when present in its homozygous form, the c allele cancels out ANY other variety and turns the rabbit into a REW. Varieties recognized in Holland Lops that are cc at the C locus are:
~REW
C_ is normal. It can be CC, Cc(chd), Cc(chl), Cc(ch), or Cc. It is the most dominant on the C locus. Varieties recognized in Holland Lops that are C_ at the C locus are:

c(chl) is the sable gene. Sable can be either c(chl)c(chl), c(chl)c(ch), or c(chl)c. The c(chl) allele is responsible for shading of sable-based varieties (not tortoise). It is recessive to C and c(chd), but dominant to c(h) and c. Varieties recognized in Holland Lops that are c(chl)_ at the C locus are:
~Sable Point
