You are right. Axanthic radix is said to be co-dominant (50/50), not simple recessive; how that works on real litters, I don't know yet. Our first try is under way now. The snow sire has some light yellow in him, and copies of both T+, & T- albino radix. We hope to be nicely surprised, if not now, in the next generation; but whatever happens, I will document it to the best of my cheap camera capabilities.
