Below is a quoted passage from an article from theHorse. It explains new knowledge about Genes and the gaited horse.

"...Gaited horses rely on the 'gait-keeper mutation,' DMRT3_SER301STOP, to maintain their gaiting at high speed without breaking into a canter. Horses with this mutation tend to use intermediate (i.e., trotting or pacing) gaits more frequently, says Brooks.

'Racing performance and gait are much more complex than can be explained by a single gene, but this gene has a major impact on gait,' says Bailey.

In a 2014 evaluation of breeds worldwide, Swedish researchers found this mutation in 68 of 141 breeds. It was most common among gaited breeds or harness racing horses and often absent in other breeds. Bailey says selection for it has enabled its spread in Standardbreds, Saddlebreds, Missouri Fox Trotters, Paso Finos, Icelandic horses, and Kentucky Mountain Saddle horses, to name a few. ..."
