Hi there, i just got a filly that i bred and it says she is a brown rabicano sabino yet she is completely white. Can anyone explain? Thanks!

The sabino can hide the rest of her color. If you reroll it you should be able to see the brown rabi markings :)

Thank you! I also had another question. I genetics tested one of my foals and beside one it says X-

what does that mean? The genetics messes me up

X- means the horse does not have brindle. If it was X+, that would mean the horse does have brindle. Brindle is listed in the color description of the horse though, so it's not something you need to gene test for in order to figure out.
