Tobiano roaning is white ticking in the body color of a pony. The roaning is sometimes over large areas on the pony's body and other times it's small areas or roaning spots. Tobiano roaning can be present at birth or start to appear as the foal grows up.
Tobaino roaning is not associated with Classic Roan, Rabicano, or Sabino Roaning; only Rabiano is currently found in Chincoteagues. Roaning and random roan spots is a common occurrence on tobianos and is a characteristic of the pinto pattern and is not a separate inheritance. A parent having tobiano roaning does not mean their offspring will. It does appear to run in some families, but there doesn't appear to be a genetic component. The roaning tends to be more common homozygous tobianos and on horses with cat tracks, but heterozygous tobianos can also have roaning. There are other types of roaning still being researched, however most in Chincoteagues appear to be linked to tobiano.
