What is Splash?

Splash is a variable white spotting pattern that makes the horse look as if it were dipped in white paint. There can be white stockings, large white blazes, blue eyes, belly markings, and interestingly, in heterozygous (one gene carriers) there can be no white at all.

The splash gene "hides" only in the context that it isn't always visually obvious. It doesn't skip generations or express only on specific base colors. If you suspect a horse carries splash, DNA color testing for Splash 1 confirms whether or not it is present.

If a horse has one copy of the splash gene and it is mated to a non-splash Morgan the resulting foal will have a 50% chance of inheriting one copy of the splash gene, 50% will have no splash gene at all.

If a Morgan has one copy of the splash gene and it is mated to a Morgan with one copy of the splash gene, there is a 50% chance of inheriting one splash gene, a 25% chance of inheriting two splash genes, and 25% no splash gene at all. 

If a Morgan has one copy of the splash gene and it is mated to a Morgan with two copies of the gene there is a 50% chance the foal will inherit two splash genes and 50% it will inherit one splash gene. This pairing is better but still only 50% odds for a homozygous splash.

If both Morgans have two copies of the splash gene the resulting foal will have two splash genes and breeders are assured the white pattern will express maximum white. This 100% homozygous pairing is the ideal scenario for a breeder to get foals with pinto patterns. It is also the most difficult to get.

It is very difficult, and often takes a breeder years, to produce a homozygous splash foal with excessive white expression. When they are born, because they are so rare (less than 20 in the breed), they are not inexpensive and they are not sold on the open market often. As the number of Morgan horses possessing the splash gene increases, the breed may see more pinto marked Morgans and prices may eventually come down too. That will take many years to accomplish with breeders who have a passion for more white pattern in the Morgan breed. 

Our goal is to increase the number of quality splash Morgans with proven ancestry and the "icing on the cake" will always be foals that are homozygous splash - 2 copies of the splash gene.
