Thanks Asplundii. I actually prefer to know it is just the 4 genes at play. I don't mind proving something out for myself, but I wouldn't want to put an animal out into the world that is an unknown quantity. It can be challenging enough to achieve a desired result when you know what you're working with. But with unknown variables at play it's like shooting in the dark.
When you look at the pic of the Leopard Mojave Pinstripe, you wouldn't think adding a gene as basic as Pastel would change it to this extent. I guess I was really surprised that it obliterated the pattern and the color so much. She's powerful, but not very attractive IMO.
What makes you think Harlequin-like on the Mojave Pastel? I am not really familiar with the gene or it's effect on pattern.
