This research was on genetic variants influencing coat growth pattern, length, and curl.  Genome wide studies of over 1000 dogs from 80 domestic breeds were studied.  The focus was on structured patterns of fur variations to localize the genetic basis of three characteristics of the canine coat.  These three mutations in various combinations were found in 95% of dogs sampled; those included 108 of the approximately 160 AKC breeds at the time.

  1. Presence or absence of “furnishings”, the growth pattern marked by a moustache and eyebrows typically observed in wire-haired dogs
  2. Hair length
  3. Presence or absence of curl

Seven phenotypes were identified from various combinations of the three characteristics.  The Bearded Collie was in the group having long coat with furnishings with two mutations named FGP5 and RSPO2.  The article is available online to members of the AAAS; readers may contact the webmaster for more information.
