White 20, or W20, is one of a group of over 30 white or pinto patterns. They were grouped together because they're found on the same gene, called KIT. W20 was the first of this group that has been found in Chincoteagues. Visit the Sabino page learn about the others patterns in the W group.
W20 generally causes white markings like a blaze, star, snip, or socks. The W20 white markings don't have any specific characteristics that make it stand out. They look like the typical face and leg markings found on any pony. W20 is also a white booster which means it increases the amount of white if another pinto pattern is present.
There's a test available for White 20 and it was found in Chincoteagues via test. The first Chincoteague W20 was found in is Riptide's Cocoa Dream. It's found in the feral Assateague herd as she was born on Assateague. White 20 is dominant, however, you likely can't tell just by looking at a pony if it has W20 or not.
W20 is found in a wide variety of breeds. Pretty much all the breeds that have been crossed into the Chincoteague Pony have been found to have it. Because it's so widespread in the horse population it's likely a very old mutation. It may have been in Chincoteagues from the beginning. Early ponies had minimal white markings but photos from the early 1900s show ponies with face and leg markings.
