Valhalla Posted June 2, 2005 Report Share Posted June 2, 2005 Percentage of puppies in a litter that will be black or red can be estimated using the graph with the B (for Black dominant) & r (for red recessive) formula, but how about for coat length? Is smooth coat a recessive? Quote Link to comment Share on other sites More sharing options...
Rave Posted June 2, 2005 Report Share Posted June 2, 2005 Smooth is dominant. I'm not sure how the many variations of smooth play into that, or the semi-rough coats either. Quote Link to comment Share on other sites More sharing options...
MrSnappy Posted June 2, 2005 Report Share Posted June 2, 2005 I thought smooth was dominant to rough? Like, if you breed a border collie to a Lab or a Jack you almost always get smooth coat puppies. I also through I read somewhere that smooth and rough puppy litters are generally split down the middle. Maybe I need to go look that up. Edited to add: I found this information Coat length is controlled by more than one set of genes. Smooth coat is dominant over rough coat. A smooth coated dog can be BB or Bb. A rough coated dog can only be bb. So, rough + rough = rough always; smooth + smooth = smooth usually; rough + smooth = rough or smooth depending on the smooth dog's genes. on this website. So I am curious - this means that a border collie X kelpie will always be smooth coated, since kelpies do not theoretically carry a gene for rough coats, right?

Rave Posted June 2, 2005 Report Share Posted June 2, 2005 I would assume you could do the same thing for Coat length as you could for color. Quote Link to comment Share on other sites More sharing options...
Valhalla Posted June 2, 2005 Author Report Share Posted June 2, 2005 Mr. Snappy, under what heading on that website did you get that info? Quote Link to comment Share on other sites More sharing options...
MrSnappy Posted June 2, 2005 Report Share Posted June 2, 2005 under the "About Border Collies" section, there is an FAQ of sorts and this was "Genetics for common folk" or something similar. RDM Quote Link to comment Share on other sites More sharing options...
