Basics
The base colors of the sabertooth tiger's coat are determined by two primary loci (genetic locations) affecting pigmentation: the E locus (extension of color) and the A locus (agouti).
E locus (Extension)E (dominant): Full color expression
e (recessive): Recessive allele leading to red mask or no color
A locus (Agouti)A (dominant): Wild-type distribution (striped/patterned)
a (recessive): Solid color coat without striping
Base Colors:
ColorsBlack (E_/A_): (EE or Ee/A_) Dominant black coat with patterns.
Brown (Ee/A_): (ee/A_) Dark brown color with a wild-type pattern.
Cream (ee/aa): Pale, almost white with solid coloring.
Dilution Variants
Dilution affects the intensity of the base colors:
Full Dilution (D): Lightens the overall color
D: Diluted (light color)
d: Non-diluted
Examples of Diluted Colors Only possible if Extension gene is ee
Fawn (D_/Ee/A_): Diluted version of brown
Silver (D_/ee/aa): Diluted version of cream
Ivory (D_/E_/A_): Diluted version of black
Patterns:
Patterns are influenced by additional loci, the most notable being the S locus and the P locus.
S locus (Spotting)S (dominant): Spotting and stripes are present
s (recessive): No spots, solid patterns
P locus (Pattern Type) Only shows on E_ or e_/aa
P (dominant): Large spots or rosettes
p (recessive): Stripes or flecks
Pattern CombinationsWild Patterned (A_/S_): (AA/SS or Aa/Ss) Traditional sabertooth stripes.
Spotted (aa/S_/P_): (aa/S_/PP or aa/S_/Pp) Large spots scattered.
Thin Striped or Flecked (aa/S_/pp): Thin striping or Flecks.
Mutations
Various unique mutations may arise, which can add novelty to the coat color and pattern. Mutations will only be passed if Both parents have at least one copy (G_/Gl_/Bi_) of the mutation. It is possible for multiple mutations to show at the same time. Mutations can also be rolled for if parents have no mutations. (Mutation chance is 10% for 1, 5% for 2, and 1% for all three)
Known Mutations:Ghosting Mutation (G): Causes fading of pigment, letting underlying colors show through. (Similar to roan in horses)
Glitter Gene (Gl): Adds a sparkling effect to the fur, most noticeable in sunlight. It can be dominant or recessive.
Bicolor Mutation (Bi): Creates two distinct colors on the body, often in a split pattern. (Similar to Chimera but does not stem from Twins)
Genotype for MutationsGhost (GG to show): Faded appearance, light patches appear.
Glittered (GlGl to show): Sparkling fur gene affecting all coat colors.
Bicolor (Bi/Bi to show): Essential changes showcase vivid distinct halves.
Examples:
Example Genotype:
EE AA SS dd GG GlGl -> This results in a wild patterned black sabertooth with fading coat, and sparkling sheen mutations.
