BeltedLab name: Belted
Fancier name: Belted (sometimes described as banded)
Genotype: bt/bt
Chromosome: 15
Originated: Spontaneous mutation (Point mutation)
Show class: Belted mice are usually shown in the Banded class. Genetically belted mice often make the best examples of Banded in show.
General description: Belted mice resemble banded mice with a band around their mid-section. Opposite to Banded, the white band on a Belted mouse starts on the back and is usually thicker on the back. The white band then goes down the sides of the mouse and around the belly. Belted mice generally have a thinner stripe on the belly, in comparison to the back. However, they can be bred to have the most perfect, even, band.

AstrexLab name: Banded
Fancier name: Banded
Genotype: Wbd/* (note that other genotypes can *look* banded and be shown in a Banded class. Some of these genotypes include:
Belted: bt/bt.
Sash: Wsh/* Chromosome 5. (however, Sash usually makes BEW visually)
Sometimes Piebald s/s.
Chromosome: Banded is found on chromosome 5.
Originated: Spontaneous mutation
Show class: Banded
General description: Solid mouse with a white band completely around the midsection. White band if usually wider and starts on the belly. Double BandedThe white band then goes up the back. Good banded mice will have an clean, even band all the way around. However, some will have broken bands, not connecting at the spine or only going half way around the mouse. The band is often covering the mouses' belly entirely or close to it (considered a fault). Band can also be extremely wide, consuming 1/2 of the mouse. Banded can also cause 2 white bands around the mouse, often referred to as Double Banded. Double banded often occurs in homozygous banded mice (Wbd/Wbd)

Pictured: Top: Banded Black Tan (head and nose spot on this one is a fault). Bottom: Double Banded Black (colored bands "should" span all the way around mouse, unlike this one)

BrokenBlackLab name: Piebald
Fancier name: Piebald (also "Broken")
Genotype: s/s
Chromosome: 14
Originated: Spontaneous mutation (very old mutation, dating back to around the 1920's)
Show class: Piebald can look like many show classes depending on spotting pattern;
Broken: The mouse should have clean cut, even spots. Both white spots and colored markings should cover 50% of the mouse.
Even Marked: Spots should be clean-cut and spread evenly throughout the coat. Spots should mirror each other on both sides of the mouse.
Even MarkedDutch: For description, see Dutch below.
Banded: For description, see Banded above.
General description: Piebald is often referred to as "cow marked" (slang) because of its tenancy to distribute cow-like markings. However, they can mimic a lot of different spotting genes.

Pictured: Top: Broken Black. Bottom: Even Marked Black (this isn't the best example of Even Marked but close. Spots should completely mirror each other. This mouse has very small faults)

DutchLab name: Unknown (if there is a gene for dutch at all)
Fancier name: Dutch
Genotype: Unknown. Some fanciers believe there is a gene which causes the dutch pattern while others believe that it's one or a combination of: piebald, banded, sashed, and/or belted.
Chromosome: Unknown (if there is a gene for dutch at all)
Show class: Dutch
General description: Markings include: oval shaped patch starting at the front of the eye and going to the back of the ear on both sides of the face. DutchThis marking should not touch the whiskers. A white stripe should be apparent, yet very narrow, between the dark face markings starting at the nose and going around the ears. They should also be marked from the hips back, leaving the front half of the mouse white. Spots should be clean cut. Dutch can come in any color.

Top picture: Ideally, the saddle (black rump marking) should consume more of the body and be cleaner cut. The face marking should be rounded better and go around the back of the ear aswell.

Broken MerleFancier name: Broken Merle
Genotype: See Merle and all white spotting genes.
Show class: Broken Merle
General description: Broken merle is a combination of white spots, Roan, and Merle in patches throughout the coat. Any spotting gene can be used to make the white spots of a Broken Merle. The amount of white spotting should coincide with the spotting gene used. Solid merle and roan patches should be split evenly, each consuming half of the body and distributed nicely throughout the coat. Broken Merle can come in any color with eyes to match.

Broken TanFancier name: Broken Tan
Genotype: See Tan and all spotting genes.
Show class: Broken Tan
General description: Spotted tans can consist of any type of white spotting with a tan belly. The amount of white spots should coincide with the spotting gene used. Spotted tans can come in any color with eyes to match. Spotted tans should not be confused with Tri-colored.

VariegatedLab name: Dominant Spotting
Fancier name: Variegated
Genotype: W/w
Note that W/W is lethal.
Chromosome: 5
Originated: Very old spontaneous mutation (point mutation)
Show class: Variegated
General description: White spots should be very jagged and spread throughout the coat. Variegated can come in any color with eyes to match. VariegatedVariegated should not be confused with Splashed. Splashed is color on color where as variegated is a spotting pattern, white spots on a colored mouse.

Pictured: Both are Variegated Black. The mouse pictured on the top is a better example of the variety.

RumpwhiteLab name: Rump White
Fancier name: Rump White
Genotype: Rw/*
Note that Rw/Rw is lethal.
Chromosome: 5
Originated: Radiation induced (Inversion)
Show class: Rump White
General description: Colored mouse with white rump. White spotting covers the front of the hips, all the way back including the tail. The line breaking the spotting and colored part of the mouse should be well defined and even all the way around mouse including the belly.

Pictured: Rumpwhite
owned by Annemarie van Dam, Mousery Kennedy and bred by Mousery Narbo-Huan
Ideally, the rump line should be cleaner cut than this mouse.

Colored RumpLab name: n/a
Fancier name: Rump Black or Colored Rump
Genotype: These mice are highly likely a result of "bad" distribution of other spotting genes (likely resulting when combining more than one spotting gene which sometimes causes PEW, BEW, and highly over spotted mice of varying patterns such as this).
Chromosome: see other spotting genes.
Show class: None at the present time. Good examples of these mice are hard to find and reproduce.
General description: Rump Black/Colored Rump is the exact opposite of Rump White. Colored Rump mice should have a colored rump, from hips to tail, with the entire top of the body white. Line should be well defined and even all the way around mouse.

Tri ColorLab name: See Splashed and spotting genes as well as the [learn more] link below.
Fancier name: Tri Color
Genotype: See Splashed and spotting genes as well as the [learn more] link below.
Show class: Tri Color
General description: Tri colors consist of 3 "visual" colors, patched evenly throughout the mouse. Each "visual" color should cover 1/3 of the mouse in even patches. Tri colors should look as if the patches are over lapping and be well defined. Tricolors can come in many different colors with eyes to match. Tri colors are not to be confused with Spotted Tans.
