The Sandblast gene is coming up incorrectly when using the Calculator. At the moment we consider the gene dominant but suspect it is incomplete dominant.
The calculator shows Sandblast bred to pied making Urban Camos but it would only produce normal het Pieds and Sandblast het Pieds. Urban Camo is a combo of Sandblast Super Cinnamon, Pastel/Super Pastel, and het pied.
I hope this helps. I’ve had to turn away quite a few people that were not clear on how to produce Urban Camos.
If there is anything you need me to help with please let me know.
