Which specific genetic factor is responsible for the luster and purity of the White Yokohama plumage?
Answer
Genes for dominant white
The striking characteristic of the White Yokohama variety is its brilliant, pure-white feathering, which emphasizes the structure and length of the tail. This consistent purity and notable luster are directly attributed to the genetic makeup involving genes classified as dominant white. This genetic expression ensures the plumage maintains its high degree of whiteness and shine, rather than displaying mixed patterns or muted tones.
