Yellow: Dominant and homozygous-lethal. One copy gives the gold Italian / Manchurian look; chicks that inherit it from both parents die in the shell, so every living gold bird carries exactly one copy.
The same Yellow mutation as the Italian — the Manchurian label reflects selection history (often meat-line stock), not a different gene.
Same Yellow (Y) mutation as the Italian, so the same math applies: no living bird is homozygous, gold × gold loses a quarter of the hatch in the shell and throws some brown chicks, and gold × Pharaoh is the loss-free pairing. Manchurian and Italian labels mostly reflect different selection histories on the same gene.

Extended Brown (E) is incompletely dominant. Two copies (E/E) make a Tibetan; one copy (E/e+) makes the lighter, rusty-chested Rosetta. That means Tibetan × Tibetan breeds true, while Tibetan × Pharaoh gives you all Rosettas — a tidy, predictable system that makes this family great for learning genetics.

Quail Keeper Max stores every bird's variety and celadon status, builds 4-generation pedigrees, and predicts the hatch from your actual pairings — so the invisible carriers in your covey stop being invisible.
