wat is Sable means??
In SV, there is no sable or dark sable. They only recognize grey or dark grey. Grey & dark grey carry the 'aw' in the chromosome, where the black & tan/bi-color carry the 'as'. Last but not least, the solid black is a recessive 'a'. you need 'a+a' to have a black dog.
The varient in each pair of gene do have a so called 'color modifier' which will be then shown in what you see in the dog or phenotype. This will then diffentiate the tan, red, silver, in GSD.
P/S : this is just the tip of the iceburg....in real, genetics is not as easy to understand and predict. no common chart to represent the gsd coloration as well. They're something not too easy or not possible to plot them out on the chart or graph.
