There is not enough correlation between the "paw-prints" and zygousity for it to be a useful marker. In fact, in all the horses I have looked at, I am pretty sure that pawprints are just random. They seem to be 50/50 - half the horses with pawprints seem to be heterozygous, half seem to be homozygous.
Having said that, I wouldn't consider what your girl has as paw-prints. On the feet, they are ermines, and common in tobianos. As for on the neck, it looks like a random spot of colour to me.
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.
