That's the way I interpreted it as well. Thanks.
More interesting bits about the action of chinchilla alleles (and their associated iris color genes) are in Cindy Haenszel's "Color Genetics in U.S. Domestic Rabbits" c1997-2010. She writes:
- dark chinchilla; full amount of black pigment; very little or no yellow pigment
; typical chinchilla when with agouti gene; blue-gray or marbled blue eyes, but may be bred with brown eyes; also may be written as cch3
- medium chinchilla; between cchd
in amount of pigment; also may be written cch2
; little known and rarely mentioned; debatable whether or not present in U.S. rabbits
- light chinchilla; may also be called sable gene or shaded gene; reduced amount of black; no yellow pigment; color shaded; typical sable when with non-agouti/self gene; also may be written cch1
; somewhat temperature sensitive; brown eyes with a red glow to the pupil
She further notes that "...although the cchd gene is dominant to the cchl gene, the brown eye color
normally associated with cchl is dominant to the marbled bluish-gray eye color sometimes associated with cchd! A rabbit with a cchdcchl genotype will have black pigment in the coat from the cchd gene, and brown eyes from the gene linked to the cchl gene. Originally, this bluish-type eye color may have been closely linked to the cchd gene, but since all the chinchilla breeds and varieties in breeds (except Angoras and Lops), have been bred for brown eyes for so long, these almost always brown eyes now. Chinchilla colored Angoras and Lops haven't
been bred specifically to have brown eyes, so they sometimes have the original bluish eyes..."
*FootNote: Although not determined by a C-series gene, iris color is determined by a gene very closely linked to this C-series gene.
