GSD Color Coat Chart

I've made a text-selectable Adobe Acrobat version of my color coat chart available.

Explanation of it's use can be found at http://www.ehretgsd.com/genetics.htm

The chart is wonderful, thanks a lot. Do I understand that there is one locus for coat color with four alleles: a, as, at, and aw with aw dominant(partially?) to everything else, as dominant to at and a, and at dominant to a? I guess I should look at your explanation. Anyway it's great. Mary Jane

You've probably explained it better than I have [img]/ubbthreads/images/graemlins/01_smile.gif[/img] There is, however some debate that the bicolor ("at" allele) is not actually determined in the agouti locus. But for all intents and purposes, this melanistic feature is included "supposedly" without affecting the reliability of the chart.

Looks good, but the white letters are kinda hard to read. Just a thought, but nicely done!

Angela,

Good idea [img]/ubbthreads/images/graemlins/03_wink.gif[/img] I outlined the white lettering with shadow (no other color seemed to stand out any better). If you go to the page and refresh you should see a difference. Probably best viewed at about 150% magnification.

Nevermind--answered my own question. [img]/ubbthreads/images/graemlins/01_smile.gif[/img] Cool chart, btw.

Well ok I suck at reading thisLOL. I have a (black)Sable, both sire and dam are Sable. On sire side grandsire is a (black) Sable and Granddam is a Bicolor. On dam side the grandsire is black/tan and granddam is a Sable. With this info can one determine what type(aw+aw, ect) of Sable my dog is?
If one wanted to breed for a specific color how do you determine what color to breed to what? DISCLAIMER: I am not a breeder and have no intentions of breeding.
Thanks

Your puppy is either Sable carrying Sable, Sable carrying black, or Sable carrying black and tan.....it is not that easy to figure out due to the presence of the Bi color bitch...they usually carry black so you do not know what the sire inherited from his dam, black or black and tan....do you know what the other colors were that appeared in your pups litter?

Why do you say your puppy is a black sable? Do you have photos of him you can share? Especially of his legs feet and stomach area? lol

OK, I went and looked at your photobucket bucket page lol I would agree he is a black sable...with my hypothisis I feel he is a sable carrying black. I say this because I feel that black sables are actually sables carrying black that also inherited the bi-color patterning.....my guess is that if he were bred to a black bitch you would get nothing but sables and blacks.

Ok me again lol I went and looked at your boy's pedigree and it notes colors....it looks like his sire was a Black and tan from a sable sire and a black and tan dam that had a black sire (so we know the gene was there as the your dog's sire was black and tan and had to carry black...now the dam was sable with a black dam so we know for certian that the dam carried black...so the available color genes to your boy were sable, black and black and tan...but two possible chances of the black gene...based on his coloring I would say he is sable carrying black (sorry if this post is all out of wack I was interupted by a phone nutrition consult and now I forget where I was going with this lol)
