What contrast exists between the APA and Entente Européenne Wyandotte color lists?

Answer

The Entente Européenne lists thirty colors while the APA lists nine.

Although all Wyandottes share the same species classification, the number of recognized color varieties differs substantially depending on the international regulatory body reviewing them. The American Poultry Association (APA) officially recognizes nine color varieties for the standard bird. In contrast, the Entente Européenne recognizes a far greater number, listing thirty different colors. This divergence shows that local acceptance and interpretation of genetic expressions lead to variations in breed standardization, even when the underlying taxonomy is identical.
