First off, what you're thinking of is "pinto", not "Paint". A Paint is a horse registered with the APHA. A pinto is any horse that has a white pattern that displays more than "high" white - more than leg and face markings really.
As I said, there is more at play. We have documented evidence of tobiano horses that have "minimal" white when they are homozygous for tobiano. Some just have a single sock, or no white at all. So yes, breeding to a homozygous tobiano, for example, guarantees that the foal will have a copy of the tobiano gene. However, this is no guarantee of pinto markings.
Mods, grant me the serenity to see the opinions I cannot change, courage to change the ones that should change, and the wisdom to spot the trolls.
