pedigree - background
The word ‘pedigree’ was initially applied to the genetic background of an animal and it is still used in that sense in a specific way. However, in general use, the term has been adapted to refer to the history of somebody or something, including their lineage, heritage, achievements, experience, etc. In other words, ‘pedigree’ is most commonly used in relation to credentials.
