Does your horse have the genetic potential to be a four-gaited or five-gaited horse?
Genetics play a crucial role in whether a horse can perform flying pace or not. Research has identified the gene and “gait-keeper mutation” that permits this gait. It has been shown that flying pace has a very simple genetic inheritance pattern in Icelandic horses and that a horse needs to have two copies of the genetic variant permissive for pace (A) in order to perform the gait.
SynchroGait® is a great tool to plan breeding of four-gaited horses
A horse shown as four-gaited at a breeding field test may be AA, CA or even CC. When these are used in breeding they will produce very different kinds off offspring.
How can this test help you?
- Test breeding animals and then cross the combination that optimizes the chances of getting offspring with the gaits you prefer
- Breed two four-gaited horses but eliminate the risk of CC offspring
- To predict the gaits of a youngster that has at least one four-gaited parent
- If you are not sure whether you should initiate pace training with your horse, to avoid pressuring CA and CC horses in attempts at flying pace

Research results in brief
- Among over 400 tested five-gaited horses, all were AA except for 13 CA-horses. However, the average score of the CA horses for pace was 5.92
- The distribution among horses shown as four-gaited at breeding field tests was 52% CA, 3% CC and 45% AA
- CA horses had a significantly higher average score for the basic gaits of walk, trot, canter and gallop
- AA horses had a significantly higher score for tölt. However, there was no difference for “slow tölt”
- CC horses are often very difficult to put into tölt in the beginning of their training (CC= 5.1, CA= 4.0, AA= 2.2*)
