Rabicano is a pattern of white hairs sometimes confused with roan. It consists of white hairs interspersed in a faintly brindled pattern along the flank area, belly and up between the front legs. It also causes a "coon tail" of white banding at the tailhead. Rabicano horses can have such minimal expressions of the pattern that it is missed. The rabicano gene is dominant, so rabicano horses will have at least one rabicano parent. Rabicano is comparatively rare in the Morgan breed.

DIA H SNOW GOOSE (DJB Yukon Jack X Dia H Dark Sprite), 1999 flaxen chestnut rabicano mare, shown here with her 2003 bay Morab filly, RGR Dance of Joy (left photo). Notice how the roaning starts on "Glory's" underside in the flank area, and becomes faint brindling along her sides. She has the white hairs at the top of the tailhead, aka "coon tail" or "squaw tail", that are typical of rabicano as well. Photos courtesy of Susanna Schaenzer.

Roan is a pattern of white hairs over the horse's body, mixed in with the base color hairs. The points and head remain the base color. As with all the patterns of white, there are degrees of expression, so that some roans are nearly white on the body while others remain fairly dark. Roan is dominant, so all roans have at least one roan parent.

In Morgans, there are two known sources for roan, the 1964 chestnut roan mare Doll Rose (out of the roan mare Rosemont), and the 1940 chestnut roan mare Torchy (out of a roan, X registered daughter of Mansfield). Doll Rose's roan line was represented by the late Caduceus Herod, a blue roan gelding pictured below. Torchy's line comes down to us through the Double J prefixed horses, and their only recent roan descendant was the 1985 bay roan mare Viv LaMae (Double J Apollo X Carlyle LaMae), who was never bred. As a result it was thought that the roan gene might be extinct in our breed.

There are a few documented cases in other breeds of KIT mutations resulting in what are known as “de novo”—or spontaneously occurring—true roans. These horses do not have a roan parent; their coloring is due to a random mutation in KIT. The New Zealand bred bay Thoroughbred stallion, Catch A Bird, is the most well-known example of this phenomena. Catch A Bird had what looked like white brindling over his body, which is not a typical roan phenotype. Roan is not known to exist in Thoroughbreds, but four of Catch A Bird’s foals had the classic look of a dark headed roan. Would it be possible that the same thing could happen in Morgans, potentially bringing roan back to our breed? For many years that has been the hope for fans of the colorful Morgan. In 2018 at Caroline Tarr’s Belvue Stud in South Australia it actually happened. Watching Moonshadows (Mt Tawonga King (black) x Mt Tawonga Sophia (bay)) is a true dark headed roan. She has produced two offspring so far, a chestnut filly and a chestnut roan colt who can be seen below.
