Moving one step lower on the c-series ladder, we find light chinchilla cchl, with no yellow pigment in the coat whatsoever and only two units of black pigment with which to colour the fur shaft.
Since this is
the c-allele responsible for producing our
of Netherland Dwarfs, you have
to mentally substitute 'shaded'
for 'light chinchilla' in order to understand
The agouti-patterned light cchl is not a recognised variety of Netherland Dwarf. What is described by the term "Sable Agouti" is the "Ghost Chinchilla". Since the agouti pattern A gene allele bands the fur shaft, dividing the black and yellow pigment into distinct zones - the Sable Agouti appears with an intermediary band coloured differently from the base and tip. Since there is no yellow pigment at all in the fur shaft, there is no underlying colour on any portion of the hair shaft, this leaves the intermediary band area unpigmented, therefore, white. There are two units of black pigment covering this white fur shaft at the base and tip. However, with only two units of black covering this otherwise 'bare' hair shaft, the colour is weakened from the true black of the full colour and dark chinchilla rabbits to a dark brown in the Sable Agouti. The Sable Agouti resembles the Chinchilla in having a fur shaft that is darkly-coloured at the base, light in the middle portion, and darkly-coloured at the tip. It is easy to confuse the Sable Agouti with the genuine Chinchilla and occasionally Sable Agoutis are exhibited at shows but usually recognised as being "poor in colour" for a Chinchilla as the fur tips of the Sable Agouti are, after all, dark brown instead of the jet black of the agouti-patterned dark chinchilla Chinchilla.
a light chinchilla
is the Marten Sable
and Siamese Sable respectively. Should
the Dwarf inherit a pair of light chinchilla cchlcchl
alleles, it will be a Dark Sable. Except for
the white belly and ticking, the tan
pattern Marten Sable is essentially the same colour as the
self-patterned Siamese Sable. With
hair shaft is void of the underlying yellow pigment, but is covered root to
tip, by two units of black pigment. The
two units of black can only achieve a brown colour as compared to the black
produced by the four units of black pigment present in the full colour C and dark chinchilla cchd
alleles. We also observe the effect
the light chinchilla cchl
allele has in producing darker colour where
the fur is shorter and the pigment more concentrated in the extremities (head, ears, legs and
feet, and tail).
To produce a medium
sable, the light chinchilla
gene allele must be inherited along with one of the lower c-alleles.
The effect of this genotype results in lightening the overall colour of
the dark sable
to the medium shade sable.
Here again, in order to produce a correctly-coloured
Siamese Sable, the light chinchilla cchl
allele must be inherited along with either himilayan ch or albino c to lighten
the Seal to the desirable medium Siamese Sable.
