Researchers uncover multiple genetic paths that lead to mottled feathers in chickens
Researchers at Texas A&M have discovered that the 'mottled' feather pattern in chickens is caused by at least three independent genetic mutations. This finding challenges the assumption that similar physical traits in domestic animals always stem from a single genetic origin.
Why it matters
This research advances our understanding of evolutionary genetics and how human-led selective breeding influences animal biodiversity.

Add to Preferred Sources Credit: Unsplash/CC0 Public Domain The white-tipped feathers found in many chicken breeds may look like variations of the same decorative pattern, but new research shows that they do not all share the same genetic origin.
Researchers from the Texas A&M College of Veterinary Medicine and Biomedical Sciences (VMBS) found that at least three independently occurring mutations involving the same gene can produce mottling, a pigmentation pattern characterized by white feather tips.
The findings, published in Animal Genetics , provide insight into how selective breeding and human preferences have shaped the diversity seen among domestic chickens.
