Tibetan Mastiffs Acquired High-Altitude Variants From Tibet Grey Wolf

Dec 07, 2016

|

NEW YORK (GenomeWeb) – By interbreeding with local grey wolves, Tibetan Mastiffs acquired gene variants that provided them with adaptations to a highland environment.

Tibetan Mastiffs adapted quickly to high altitudes over a short amount of time. They have, for instance, thicker coats and lower hemoglobin levels than low-altitude dogs. But how these adaptations arose has been unclear.
