I think negative too. Again, it's visual for me. I see no front white, and face white at the top of her head instead of the bottom. Having said that, however, I have not seen any SW2 or SW3 positives yet, and am very interested in how they present phenotypically. Has she been tested for frame or tobiano out of curiosity?
Yes they can hide but this pedigee has no unknowns in it. Each and every horse is well documented and I know and have seen too many of the get of all these horses and non have had any that can not be explained by the other side of the pedigree. Toby hiding for what 8+ generations? Posible but highly unlikely with all the horses produced from each of these lines.
