There's zero sign of the masque gene in this line. Even the "possible" goldens with their weird head patterns don't have split belly checkers or any other sign of masque. However, I also don't see it being a part of the Golden gene or anything; the original Golden, her kids, and her grandkids did not have this odd head pattern. I'm not sure if it is from the other side of the line (these kids' caramel het lava motley grandparent) or if it's just an odd coincidence. I do not think it's the masque gene, though. Especially since neither parent shows it either.
