Test duration 3-4 weeks after arrival of the sample in shampoo the lab. Material, the dna test is performed out of edta blood or or 20-30 hair roots from mane or tail. Test kits can be ordered free of charge. If hair is sent in, possibly the genetic material is not sufficient to barbie run the test. In this case it would be best to send in an edta blood sample. Testing procedure, please send in your sample together with the lab order genetic. Results will be transmitted optionally via post, fax or email. After completion of the test you will receive a separate invoice. Payment can be made via credit card or bank transfer. Breeding club discounts apply if a copy of the membership card is sent together with the respective samples. Due to administrative reasons the invoiced price can not be altered subsequently.

Characteristic and trait of inheritance, dun is a dominant gene that dilutes the color of body hair, leaving the points and head unaffected. Dun dermatitis horses also show "primitive markings" consisting of a dark dorsal stripe, leg barring, shoulder stripes and concentric marks on the forehead (spiderwebbing, cobwebbing). The dorsal stripe appears to be a consistent feature of dun horses while the other "primitive marks" vary and may not all be present, or visible. The effect of the dun gene on the base colors of chestnut, bay and black produces horses with shades that range from apricot, golden, dark gray, olive, and many, more subtle, variations. Dun is inherited independently of other coat color genes and can occur in combination with any other genes that modify the base colors. The specific mutation that causes Dun has not yet been identified, and there is no direct test for the gene. Vgl has identified dna markers associated with Dun that can be used to determine if a horse has the dun gene and how many copies.

By contrast, horses which lack a functional agouti gene cannot produce such alternating bands, and thus have wholly black coats with no visible phaeomelanin. Chestnut horses lack the ability to manufacture eumelanin altogether, and so have wholly red coats devoid of true black pigment. 5 bay silvers retain their reddish body color with black points diluted to silver. While the role of pmel17 is not fully understood, the silver dapple gene exclusively produces dilution, or hypopigmentation, of eumelanin. 2 The dilution changes black into various shades of platinum, silver and flat grey, though the original black-brown character of the color is usually preserved. The effects of the gene are more striking in the mane and tail. Horses with chestnut or chestnut-family coats - such as palomino, red roan, or red dun - are therefore unaffected by the gene and may silently carry it and pass it on to their offspring.
American horse breeds known to have the silver gene include the morgan, american Saddlebred, missouri foxtrotter, tennessee walking Horse, and the American quarter Horse. European draft breeds such as the comtois and Ardennais also occur in silver. 2 Historically mannen the color was found in the dutch Groningen, but the breed was crossbred to produce the dutch Warmblood and underwent subsequent genetic bottlenecking, so the gene may no longer be present. Inheritance and expression edit The front two rocky mountain Horses have the silver dapple dilution. The silver dapple trait is caused by a missense mutation (labeled Z ) in the pmel17 gene on horse chromosome.
It is transmitted by autosomal dominant inheritance (simple dominance). Pmel17 is active from quite early in embryonic development through to the mature cell's melanosome and is involved greens with the production of the black pigment eumelanin. 2 Melanins, which provide color in the eyes, skin, and hair, are found in two types: eumelanin, which produces black to brown pigment, and phaeomelanin, which produces red to yellow pigment. Most horses can produce both types; the brown appearance of a bay horse's coat is caused by alternating bands of eumelanin and phaeomelanin, for which the agouti gene is responsible. Eumelanin predominates in the legs, mane and tail of bay horses.

"Sooty" palomino : Dark palominos may be hard to distinguish from silver dapples, particularly if the mane or tail of a palomino contain streaks of silver. A true palomino, with a red-based coat, will exhibit yellow μαλλια or gold tones; a silver horse, in contrast, is by definition black-based and exhibits gray, black or brown undertones. A sooty palomino, like other creme dilutes, may have brown eyes a shade lighter than average, 4 but this is not true of silver dapples. When actual color is in question, pedigree information or a dna test can help clarify matters. Prevalence edit silver dapple foal exhibiting typical wheat-colored coat and pale eyelashes Many breeds do not possess the silver dapple gene. The coat color is traditionally associated with the rocky mountain Horse and the miniature horse. Scandinavian breeds and their descendants such as the Icelandic horse, nordland Pony, shetland Pony, welsh mountain Pony, welsh Pony, swedish Warmblood and Finnhorse are also found in the silver dapple colors.

Carries both genes and, because gray is a dominant gene, becomes white with age) may be identified by use of dna testing. Liver chestnut : Silver dapples, especially toppik bay silvers, are frequently misidentified as liver chestnuts or flaxen chestnuts. Flaxen manes and tails in chestnuts tend to have honey or red tones, while the pale manes and tails of silver dapples are soot-toned and darker at the roots. Liver chestnuts also lack the grey-brown dappling on the lower legs. The darkest liver chestnuts often have a kind of marbling on the lower legs, though this hair, too, should show red or yellow tones. Overall, chestnuts of all shades have red-yellow character to their coats, while silver bays recall grey-brown. Knowledge of the pedigree of the horse in question is often useful: two chestnut-based parents cannot produce a silver bay or silver black. Dna testing can be used in the most difficult cases.
The mane and tail are usually a sooty silver, darker at the roots, beds and the legs are usually a flat, brownish-grey mottled with silver. The hair around the eyes and muzzle may also show signs of silvering. Silver dapple foals can be difficult to identify, but commonly have a pale, wheat-colored body coat, white eyelashes, and hooves with tapering vertical stripes. These characteristics fade over time. 3, red-based horses, such as chestnuts and chestnuts with other dilution factors (such as palominos, and cremello ) may carry the silver dapple gene, and may pass it on to their offspring, but will not express the gene in their own body color. Contents, silver mimics edit, the points of a bay are black, while those of a silver bay (shown here) are silver. Gray : While gray horses grow progressively lighter, silver dapples often darken with age. A silver dapple masked by gray (i.e.

Black silver foute horse exhibiting strongly diluted long hair with darker roots and flat gray, dappled body color. The silver or silver dapple z ) gene is a dilution gene that affects the black base coat color. It will typically dilute a black mane and tail to flaxen, and a black body to a shade of brown or chocolate. 1, it is responsible for a group of coat colors in horses called "silver dapple" in the west, or "taffy" in Australia. The most common colors in this category are black silver and bay silver, referring to the respective underlying coat color. 2, mature black silvers typically have sooty white or silver manes and tails with a flat, non-fading, dark grey or grey-brown body coat. The body coat frequently exhibits dapples, rings of lighter-colored hair. Mature bay silvers retain their reddish bodies, though the presence of small amounts of silver often gives them a chocolate appearance.
