If one is wondering about new mutations appearing, then the KIT gene is where you want to be looking. It seems particularly unstable and has a high number of mutations.
Other genes tend to be fairly stable, and far less likely to thus mutate. The cream one is probably in this category, although it has mutated twice - once for cream, once for pearl. Agouti is another with a few - brown bay and wild bay. I would disagree with Face though - I don't think that the recessive is necessarily the "mutation" and the dominant the "normal" gene - cream, champagne, pearl, various white spotting genes, are dominant, but we can tell that they are not the default setting for horses - bay dun seems to be the logical base to be honest. Even zebras are proving to be dun under all those stripes.
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.
