Do these showlines carry the black recessive gene? - Page 2

Well.... I think that it IS remotely possible!
The dam HAS black in her background through VA Frei de Gugge. Back pretty far but still in there! Didn't do a total search so there may be others?
Sure enough! Here's a bitch in the dam's background that produced a solid black in a different line from the Frei line that I found...http://www.pedigreedatabase.com/german_shepherd_dog/dog.html?id=14288 

Oh gees..... I hate it when I get started... lol I'll post more if I find more...


I had a SL that carried solid black. He went back on Frei also.

It's always possible for a recessive to hide in a line.  How many times have people seen livers or blues pop up when nothing has been seen of them in 6+ generations?  The gene has just been passing down the line but until bred to a carrier it's not going to show up.

As for dominant black, I actually know three confirmed ones now.  Two are from the bloodline (European) and the other I don't know the pedigree on (pet lines).  I know the pedigree is correct on the first two for at least two generations but I can't say for sure further back than that and it's likely been in the line longer than two generations (solids for several generations that I know of but not sure how far back - not a pedigree that interests me).  I guess it would be pretty easy to miss dominant blacks though considering we just assume a black dog is recessive a/a.  It could travel down a line of blacks without anyone thinking anything of it until the dog was bred to a dog that definitely did not carry recessive solid.  Not saying that's definitely what happened but it is a possibility to take into consideration.
