DNA From Domesticated Chickens Is Tainting Genomes Of Wild Red Junglefowl, Finds Study

The red junglefowl—the wild ancestor of the chicken—is losing its genetic diversity by interbreeding with domesticated birds, according to a new study led by Frank Rheindt of the National University of Singapore published January 19 in the journal PLOS Genetics.

By comparing modern wild genomes to genomes of red junglefowl from approximately a century ago, the researchers estimate that the  have inherited 20% to 50% of their genomes from domestic birds, depending on their location. The study also identified eight genes that differed greatly between domestic chickens and their wild ancestors, and which were likely key to developing the chicken as a livestock animal. These genes are involved in development, reproduction and vision.

The results of the study bring to light the ongoing loss of genetic diversity in the wild junglefowl, and the researchers suggest that efforts may be needed to protect its .

Additionally,  have value for agriculture because they can serve as a reservoir of genetic diversity that researchers can tap into to improve domesticated species—for example, finding genetic variants that make an animal more resistant to a particular disease. Losing that genetic  in red junglefowl may hinder scientists' ability to safeguard one of humanity's most important food sources.
