DNA test

  • The DNA test verifies the presence of 2 mutations of the TBX3 gene responsible for Dun dilution and primitive markings. 

Sample

  • 20 to 30 - hair roots - envelope
or
  • 5 mL - blood - K3 EDTA tube

Turnaround time

  • 2 to 5  working days

Why test?

  • The DNA test that will provide information for both dun dilution (D) and the primitive markings (nd1, nd2). 

Results description

  • D/ - 2 copies of Dun. Horse will have Dun dilution and express primitive markings. Dun will be passed on 100% of the time.
  • D/nd1 - 1 copy of Dun and one copy of nd1. Horse will have Dun dilution and express primitive markings. Horse can pass on Dun dilution or primitive markings without dilution.
  • D/nd2 - 1 copy of Dun and one copy of nd2. Horse will have Dun dilution and express primitive markings. Horse can pass on Dun dilution with primitive marking 50% of the time.
  • nd1/nd1 - 2 copies of nd1. Horse will not be Dun diluted. Varying levels of primitive markings are present. Horse will pass on nd1 100% of the time.
  • nd1/nd2 - 1 copy of nd1 and one copy of nd2. Horse will not be Dun diluted. Varying levels of primitive markings are present. Horse will pass on nd1 50% of the time.
  • nd2/nd2 - Horse is not Dun dilute.

Additional information

  • Dun is a dominant dilution gene of equines characterised by lightening of the body color, leaving the head, lower legs, mane and tail undiluted.
  • Dun is also typically characterised by “primitive markings” consisting of a dark dorsal stripe and sometimes leg barring, shoulder stripes and concentric marks on the forehead.
  • Dun is present in many breeds of horses including (but not limited to) Appaloosa, Bashkir Curly, Iberian horse breeds, Icelandic Horse, Mustang, Norwegian Fjord, Paint, Paso Fino, Peruvian Paso, Quarter Horse and several of the pony breeds
