What is the Colortest Dun?
The Dun coat color is considered as the the “wild-type state” and we can found it in wild equine like Przewalski horses, zebras etc.
The black dorsal stripe is the more visible Dun marking, however we can also observed to a lesser degree leg barring, shoulder stripes and concentric marks on the forehead.
You can find more information of horse coat color on this page.

|Test result||Colortest Dun status (TBX3 Indel + TBX3 SNP1 )||Color status|
|D/D||2 copies of Dun mutation (Indel WT/WT and SNP1 G/G)||Horse is Dun|
|D/nd1||1 copy of Dun mutation, 1 copy on nd1 (Indel WT/WT and SNP1 G/T)||Horse is Dun|
|D/nd2||1 copy of Dun mutation, 1 copy on nd2 (Indel WT/del and SNP1 G/-)||Horse is Dun|
|nd1/nd1||2 copies of nd1 (Indel WT/WT and SNP1 T/T)||Horse is not Dun. Horse may have primitive markings.|
|nd1/nd2||1 copy of nd1, 1 copy of nd2 (Indel WT/del and SNP1 T/-)||Horse is not Dun. Horse may have primitive markings.|
