Since the original study in the early part of the last century, in addition to the breeds identified as carrying the SW-1, -2 or -3 alleles, splashed white has also been identified, but not mapped, in American Saddlebreds, Morgan horses, the Irish Tinker or Gypsy horse, the Indian Kathiawari and feral Abaco Barbs of the Bahamas.

Splashed white occurs in a variety of geographically divergent breeds, from Morgans in North America to Kathiawari horses in India.
