Roan is a white patterning coat color trait characterized by intermixed white and colored hairs in the body while the head, lower legs, mane, and tail remain colored.
Mode of Inheritance: Autosomal dominant
Alleles: N = Normal, Rn = Classic Roan
Breeds appropriate for testing: Many breeds
Explanation of Results:
- Horses with N/N genotype will not have the classic roan pattern and cannot transmit this roan variant to their offspring.
- Horses with N/Rn genotype will have the classic roan pattern. They may transmit this roan variant to 50% of their offspring. Matings with N/N genotype will result in a 50% chance of producing a roan foal.
- Horses with Rn/Rn genotype will have the classic roan pattern. They will transmit this roan variant to all of their offspring. Matings with any genotype are predicted to produce all roan offspring.

Please Note: DNA testing services are limited to horses that are registered or have a pending registration.
Please Note: All DNA parentage verification and mandatory health testing results, whether purchased through the EBRA or transferred into the EBRA system, will become permanent record, which the documented owner may access at any time upon request. The EBRA is not responsible for providing non-mandatory DNA test results, therefore the release of any additional testing performed by past or present owners must be negotiated between the private parties at time of purchase.
