I am guessing Rusty Black on the left with one black (Bb) and one red (Rr) gene. Anything about the one on the right would be a complete guess other than (B?) (cg?) (Dd). I don't see the influence of a red gene in the one on the right. Bronze and slate combined can create the illusion of red without having a red gene.as can be witnessed in a Red Slate. (bb Dd).Check out this color variation! I'm guessing these two share the same parents. Dad is the tri colored blue, mom is either Annabelle (bourbon red) or pretty girl( red bronze)View attachment 2091700View attachment 2091701View attachment 2091703
One sibling displaying black and one displaying blue, both carrying one red Gene each?
