![]() ![]() Dun dilutes both red and black pigment, and the resulting colors range from apricot, golden, dark gray, olive and many more subtle variations. The expression of the primitive markings (with or without dun) in the domestic horse is variable, with the dark dorsal stripe being the most consistent and visible feature. Dun with primitive markings is considered the “wild-type state” and is found in other equids such as Przewalski horses, zebras, and wild asses. ![]() Dun is also typically characterized by “primitive markings” consisting of a dark dorsal stripe and sometimes leg barring, shoulder stripes, and concentric marks on the forehead (spiderwebbing, cobwebbing). Sorraia with dun dilution and primitive markingsĭun is a dominant trait of equines characterized by lightening of the body color, leaving the head, lower legs, mane, and tail undiluted. Matings with any genotype are predicted to produce dun dilute offspring. Horses with D/D genoytpe will be dun dilute and will transmit the dun dilute variant to all of their offspring. ![]() They may transmit the dun dilute variant to 50% of their offspring. ![]() Horses with D/nd1 or D/nd2 genotype will be dun dilute and will display primitive markings.They will transmit the non-dun 1 variant to all of their offspring. Horses with nd1/nd1 genotype will not be dun dilute, but may have primitive markings.They may transmit the non-dun 1 variant to 50% of their offspring. Horses with nd1/nd2 genotype will not be dun dilute, but may have primitive markings.They cannot transmit a dun dilution variant to their offspring. Horses with nd2/nd2 genotype will not be dun dilute and will not have primitive markings.Oftentimes, dun is also characterized by "primitive markings" such as a dark dorsal stripe, barring of the legs, shoulder stripes, and "cobwebbing" on the forehead.Īlleles: D = Dun dilute, nd1 = Non-dun 1, nd2 = Non-dun 2īreeds appropriate for testing: Andadura, Andalusian, Appaloosa, Azteca, Bashkir Curly, Caspian Horse, Connemara Pony, Criollo, Curly, Icelandic Horse/Pony, Kallblodstravare, Kiger Mustang, Lusitano, Mangalarga, Mangalarga Marchador, Miniature Horse, Morgan Horse, Mustang, Norwegian Fjord Horse, Paint Horse, Paso Fino, Peruvian Paso, Pony of the Americas, Przewalski's Horse, Quarter Horse, Shetland Pony, Spanish Mustang, Welsh Pony, related breeds Phenotype: Dun is a coat color dilution characterized by lightening of the coat, with the head, lower legs, mane and tail undiluted. ![]()
