Lab name: Viable Yellow
Fancier name: Brindle, American Brindle, Tiger Brindle, etc.
Genotype: Avy/*
Chromosome: 2
Originated: Spontaneous mutation (transposon insertion)
Show class: Brindle
General description: Stripped similar to a tiger from head to tail. Less define stripes on the belly.
Pictured: American Brindle |

Lab name: (non-agouti) Brindled
Fancier name: Brindled, Sex Linked Brindle, X-Brindle, English Brindle, etc.
Genotype: a/a Mobr/* Note that Brindled is Sex linked. Homozygous Brindled is lethal as well as brindled bucks.
Chromosome: Brindled is on the X chromosome.
Originated: Spontaneous mutation (point mutation)
Show class: Brindle
General description: Stripped similar to a tiger from head to tail. Less define stripes on the belly. They can be any color with eyes to match. Stripes on English brindles usually get wider with age.

Lab name: (non-agouti) Roan or Roan Freckled
Fancier name: Roan
Genotype: a/a Rn/* and/OR a/a Rnfkl/*
Chromosome: 14
Originated: Both were Spontaneous mutations in lab stock. Roan was first found in gremlin stock while Freckled was first found in stock carrying t-alleles.
Show class: Roan
General description: Coat is a mixture of white and any other color which is evenly distributed throughout the body. Eyes should match the body color.
Pictured: Roan |

 |
Lab name: unknown at the present time
Fancier name: Merle
Genotype: unknown at the present time. However, it is believed to be a modifier of roan or another gene which is stopping the roaning in areas, leaving solid patches (much like how the splashed gene stops c-dilute in areas).
Chromosome: -
Originated: -
Show class: Merle
General description: Coat is marble-like in color. Lighter roan body with evenly distributed patterns of a solid color. Eyes to match the base color

Fancier name: Himalayan
Genotype: a/a ch/c
Show class: Himalayan
General description: white body with define dark points on the nose, ears, feet, and tail. Pink eyes.

Fancier name: Color Point Beige
Genotype: a/a ce/ch
Show class: Color Point beige
General description: Color Point beige can look just like Himalayan but with dark eyes or they can have an off white (creamy) appearance along with the points and dark eyes.

Lab name: (non-agouti) Himalayan
Fancier name: Siamese (homozygous "Himalayan" makes what a fanciers call Siamese)
Genotype: a/a ch/ch
Chromosome: The Himalayan allele is on chromosome 7.
Originated: Spontaneous mutation (Point mutation)
Show class: Siamese
General description: Similar to the Himalayan but with larger points and nice body shading. Ruby eyes.
Pictured: Siamese |

Lab name: Unknown
Fancier name: Reverse Siamese
Genotype: Unknown
Chromosome: Unknown (likely having to do with extreme dilute ce)
Originated: Unknown
Show class: Reverse Siamese
General description: Any color mouse with bright white points at the nose, ears, feet, and tail. Reverse siamese are usually (possibly always) coffee with white points.

Fancier name: Burmese
Genotype: a/a cch/ch
Show class: Burmese
General description: Burmese can come in almost any color with dark points at the mouses nose, feet, and tail. Points are the same color as the body, just darker. Burmese can vary in shade from dark chocolate (making the points indefinable) to light brown with very dark points.

Lab name: Yellow, Tan, Umbrous-Patterned
Fancier name: Sable
Genotype: Ay/at Up/*
Chromosome: At the present time, the chromosome Umbrous-Patterned is located on is unknown.
Originated: Spontaneous mutation (First discovered in a Peru stock mouse with high frequency of non-pairing of the sex chromosomes, after introduction of the yellow allele Ay)
Show class: Sable
General description: Mouse should have a dark back fading into a red-ish-tan underside.
Pictured: The Sable pictured here is not a "true" sable, genetically. She does, however, possess an amazing likeness to a true sable. She is recessive yellow genetically. |

Lab name: Unknown at the present time.
Fancier name: Splashed
Genotype: Unknown at the present time. However, speculation is that splashed is transgenic. More about Splashed in the Tri Color section.
Chromosome: Unknown at the present time.
Originated: Unknown at the present time.
Show class: Splashed
General description: Coat has darker splashes of color on a colored mouse. Splashed can come in any color with eyes to match. Splashed is not to be confused with Variegated.
Pictured: Top: Cream splashed, Bottom: burmese splashed.
