What genetic concept explains the specific patterning seen in the Red Shouldered Yokohama?
Answer
Incomplete dominance between red and white genes
The visual arrangement and sharp contrast observed in the Red Shouldered Yokohama variety are the direct result of a specific mode of genetic inheritance known as incomplete dominance. This genetic mechanism dictates how the alleles for red coloring and white coloring interact, resulting in the precise, recognizable pattern where red appears distinctly on the shoulders against the white body plumage, rather than one color completely masking the other or producing an intermediate, blended shade across the entire bird.
