BACKGROUND: Chicken skin colour is an economically important trait influenced by consumer preferences across different markets. Previous studies established that white skin is dominant over yellow skin, with the β, β-carotene-9',10'-dioxygenase (BCO2) identified as the candidate gene. However, the precise causal mutation within this gene region has remained unidentified for over a decade, limiting the development...
