Does not alter facial points of the nose, ears or eyes.
Saddled Dun (u)
SdSd / Sdsd

xx |
xxAdds a saddle marking similar to that found in canines.
Can be seen with Regular and Wildebeest Dun, or on its own.
Dominant to regular Dun, but recessive to Wildebeest.
Sd_ / SdD _ / WdSd
Masked Sooty (r)
MstyMsty - expresses
Mstymsty - carries
xx |
xx |
xxA more solid sooty appears over the face and neck, similar to masking seen in canines.
It can appear dappled, though a solid color of dark brown or black is most common.
Will only appear if homozygous dominant.
If MstySty/StyMsty, the horse will show regular sooty but can pass Masked Sooty to offspring.
Irish Tobiano (u)
ItoIto / Itoito
xx |
xx |
xxSimilar to the Irish White marking seen in canines, Irish Tobiano limits the white to the neck, face and forelegs.
It is dominant to Tobiano, and will show even if a carrier of both regular and Irish types. (ItoTo/Itoto)
Van Splash (u)
VsplVspl / Vsplspl
xx |
xx |
xxSplash that mimics the white coverage seen in Turkish Van cats.
The ears, forehead and rump are never white. Heterozygous (Vsplvspl) may show some coat near or around the elbows.
Homozygous will never show any part of the base except the ears and rump, and the forehead marking will be broken up.
It is dominant to regular Splash, and will show even if a carrier of both regular and Van types. (VsplSpl/Vsplspl)
Lynx Grey (c)
xx |
xx |
xxA type of grey that mimics the ticking seen in Eurasian Lynx cats, it also gives a tabby look to the face.
Demoiselle Grey (c)
xx |
xx |
xxA type of grey that mimics the fade appearance in the Demoiselle Crane, leaving the head, neck and chest exposed.
Breasted Grey (c)
xx |
xx |
xxA type of grey that mimics the Rose-breasted Grosbeak, leaving the chest and throat exposed.
Quagga (l)
qaqa only!
xxA type of zebra striping that is restricted to the face, neck and shoulders, though can somtimes extend along the topline of the back and show around the knees and hocks.
It is always a ruddy brown color.
A fully recessive marking, it can be passed to offspring but will not appear unless both parents are carriers and pass one copy.
Rau (l)
+Rau
must have qaqa!
xxA type of cream or ivory colored pangare, can only express with Quagga.
Rau has a 50% chance to be passed to a foal if there is one quagga
parent!
Any quagga parent, showing Rau or not, can pass this to their foals.
If Rau gene is present in a non-quagga trotter their offspring can still receive Rau.
Thylacine (r)
ThyThy / Thythy
Tasmanian Tail possiblexxA type of striping along the spine, it can appear with as little as two stripes and as many as ten.
If there is a stripe near the base, or dock, of the tail, it can cause the tail to become a brown color.
Smoke (uc)
E_ aa +Smoke
This gene gives a silver-grey pangare effect on black bases only.
xxA type of pangare that appears in black based trotters (E_ aa) that gives a silver grey appearance to the horses soft points.
Camarillo White (r)
CwCw / Cwcw
xx |
xxA type of dominant white coat color that overrides any other underlying genes with a pale cream coat.
Heterozygous [Cwcw] is a slightly darker, more tanned version of the coat with light gray muzzle/eye skins.
Homozygous [CwCw] is a pale, nearly white cream shade with light pink muzzle/eye skins.
Roaned White (u)
RwRw / Rwrw
xx |
xx |
xxA gene similar to PATN1 that affects tobiano, overo, sabino, dominant white, and splash only when those white genes are also present in the genotype. It cannot express without a white gene present. It 'roans' out the white in a similar fashion to roan in dogs.
It can express is heavy, moderate or minimum roaned fashion.
Dun Brindle (l)
B+B+ / B+b+
xx |
xxA mutation of brindle that expresses barring and spotting on the legs and body.
Homozygous expressions have thicker stripes with less spots, socks on all four legs, and a white belly.
Heterozygous expressions have thinner stripes and more spotting than stripes.
Both always have tipped or fully affected ears and fully affected manes and tails.
Regular expressions take on the color of the coat's would-be dun factor. Reverse expressions take on a pale/shaded white color.
Okapi (c)
OkpOkp / Okpokp
xx |
xxThis marking has different states, depending upon its zygosity (dominance). In heterozygous carriers, it will only show the white barring on the legs and hindquarters. In homozygous carriers, the face shows a progressive greying that varies among individuals, and a darkening of the hind end completely, along with the white barring.
The legs will always have a split stocking, with the lower portion white being as minimum as coronets or as large as socks; the upper stocking will never pass above the knees and hocks, where it becomes barring rather than a solid marking.
Isabella (r)
ii / Ii
(carrying)xx |
xxA recessive dilute that turns the skin of a horse pink, lightens the hooves, and dilutes the coat to a shade of taupe shade.
Unlike mushroom, however, the mane and tail will not lighten, but will become a shade darker than the coat.
This gene can be seen in any base coat, it is not restricted to a certain coat.
Foals expressing this gene will have a very light coat and then darken with age, but their manes and tails will remain mostly the same shade from foal to adult.
Surgeon's Coat (c)
ScSc / Scsc
xx |
xx |
xxThis marking adds a cloak similar to what can be seen on the Blue Tang fish. It acts as a dilute and the marking will be a darker shade than the base coat, including other dilutions; it will show over any other dilute such as grey, cream, champagne and agouti factors. On black, it may appear as a lighter shade of the coat instead.
Thrush (c)
ThrThr / Thrthr
xx |
xx|
xxCan appear with the markings Tobiano, Overo, Splash, Sabino and Dominant White.
In its homozygous form, it will limit the expression on the face of the trotter to just covering the lower jaw and adding a sort of feather frill around the eyes. This is not present in heterozygous expressions of the marking, though the face may or may not be covered by the paint marking. It also adds crescent shapes from the chin, down the neck, shoulders, front of the legs and belly of the paint marking. These can be small or large, but do not go further than the knees and hocks, nor up past the midline of the horse.
Butterfly Spots (c)
BtsBts / Btsbts
xx |
xx |
xxThis marking adds spots to the legs and face of a horse; these spots tend to have alternating sizes in rows, varying from dime sized to egg sized. These spots can be seen from the shoulder and flank down in homozygous cases, with most heterozygous types showing spotting from the elbow and stifle down the legs. Spotted on the face will never go above the eyes or touch the neck.
When breeding
two butterfly spotted trotters together, there is a 1 in 4 chance that the spots can be black instead of white!
This color change is random, so two white spotted can give a black spotted, and two black spotted can give a white spotted!
The normal color of this marking is white, black colored spots are a breeding-only occurrence.
Black spotting cannot be obtained from breeding one butterfly spotted to a horse without the marking.
Bunder (c)
BuBu / Bubu
xx |
xx |
xxAdds large, circular white spots on the face, ears, shoulders and hips, along the spine and the legs. These spots can be as few as one single spot on the shoulder or face, or be as many as multiple fist sized spots along the upper body. Spots do not appear along the middle of the barrel or on the neck. It is common for smaller spots to appear in the center of larger, hollow "halo" like spots, as shown on this trotter. If white touches the base of the tail or the mane, it will change the color as with other white markings.
Chaetodon (c)
CtCt / Ctct
xx |
xxa gold, thin to thick striped marking that can be seen on the coat. It is modeled after the Butterfly Fish, the name of the marking being taken from the scientific name.
This marking is seen under white markings and sooty/jackal types. It is a common marking, and can be found on any base coat; the color itself is always a golden-yellow, though the tone may change from darker to lighter depending upon the individual. It is a marking, not a dilution, so it would not be altered by other dilutes such as a grey, pearl or brew.
This marking will never fully cover the horse, but it can cover any area; there will always be at least one stripe seen over the eyes. The stripes themselves can vary in size. There is always at least one, but no known max amount of stripes seen on a single horse. Stripes usually vary in size on each horse, with many showing both thin and thicker stripes.
Mandarin (r)
Ct_ MdMd / Mdmd
This gene is a modifier of Chaetodon, and won't express without Ct_. Mandarin curls the chaetodon stripes, often creating spirals and squares.This trotter exhibits the maximum expression possible, as it won't ever cover the entire body - just as regular chaetodon is. It may express in as few as one line. There will always be at least one line over the eye.
Marbled Splash (u)
MsplMspl / Msplmspl
xx |
xx |
xxThis gene will produce moderate to high white splashes. Color will always be present on the withers and spine with a crown to mask like face marking. Tails are will always be two toned: coat color to white.
The heterozygous expression can show the most base coat color as it can reach down to the shoulders while the homozygous expression will be nearly all white with color mainly seen along the dorsal.
For both expressions the face is nearly all white except for a mask/crown like marking by or above the eyes & the ears.
Moonspot / Moonspotting (u)
MnsMns / Mnsmns
xx |
xx |
xxThis marking is similar to paleo and grease spots; however this have a few fun twists! Based on the coat marking moonspotting for goats; it has a randomized spotting heavily throughout the body. On darker bases the spots will show lighter. Meanwhile on light bases the spots will be darker. It’s more commonly seen heavy spotted versus uncommon to see minimal spotting. Also, as shown above it has an affect with brindle similar to its own effect but reversed!
