Conservation that can be checked

A peer-reviewed study of North American domestic yaks, identified as Bos grunniens, developed genetic markers for individual identification, parentage testing and detecting recent cattle ancestry. Its importance is methodological: breeding claims can be compared with biological evidence. It does not establish that every herd has been tested or that all animals share the same ancestry. A useful conservation account should keep those boundaries visible, combine DNA results with pedigrees, and distinguish domestic yak conservation from population assessments of the wild yak.
