| Tonkinese |
Not to be confused with the Sable Siamese, which is a variety found in South Africa. Tonkinese is a dominant gene on the c-locus. Can be shown in one of the three variations:
Tonkinese
Body to be a light 'ochre' brown, with subtle gathering of slightly darker pigment on the muzzle, feet, tail, and ears. Not to be confused with the darker and warmer shade that is Burmese. Eyes are to be light Ruby or Red.
Genetics:
a/a c(t)/c
Two copies of the non-agouti gene, one copy of the albino gene, and one copy of the Tonkinese gene
Pointed Tonkinese
Body to be a mid-light 'ochre' brown, with dark sepia points on muzzle, feet, tail and ears. The face is darkest at the muzzle and eyes, but gradually blends to the body color. Not to be confused with the darker and warmer shade that is Burmese. Eyes are to be slightly darker Ruby.
Genetics:
a/a c(t)/c(h)
Two copies of the non-agouti gene, one copy of the Tonkinese gene, and one copy of the himalayan gene.
Double Tonkinese
Body is to be a rich Chocolate color with deep sepia points on muzzle, feet, tail and ears. The face is darkest at the muzzle and eyes, but gradually blends to body color. Eyes are to be a dark Ruby.
Genetics:
a/a c(t)/c(t)
Homozygous Tonkinese. Two copies of the non-agouti gene and two copies of the Tonkinese gene.

|
|
| Merle |
Body will have dark splotches/spots evenly distributed throughout a lighter coat color. The spots should be distinct and numerous. Note that they will be less prominent on a non-silvered color. Eye color to correspond to the body color.
Genetics:
Me-
One copy of the dominate Merle gene.
Faults: Too few dark splotches/spots - not distributed evenly throughout the entire colored area. Spots not dark enough to be distinct from base coat color. Other faults as for respective color/marking.
Disqualifying: No visible splotches/spots |
|
|
| Marble |
Color is gray with black markings/pattern which consists of a dorsal stripe and spots on the sides and face (most spots run together as adult). Not to be confused with Merle. Marble is not a colour on its own. It is a color modifier gene and will express on all colors, although only acceptable to be shown in black and russian blue. The color of the dorsal stripe/spots is the base color, i.e. a black marble has black stripe/spots and the gene dilutes the body color, making a gray coat color.
Genetics:
Ma/ma
One copy of the semi-dominant Marble gene.
Marble appears to be a lethal dominant gene.
Faults: No distinct spots/splashes. Lacks a visible dorsal stripe.
