This was an excellent post on coat color inheritance in GSDs...I would add that
the sex characteristic gene "y" for boys and "x" for girls, the 50/50 chance is
really not quite 50/50...the "y" sperms are faster than the "x" sperms....but
the "x" sperms are a little stronger than the "y"s.....years ago there were 104
males born for every 100 females.....Ed

Wrong? What?
=================================================
The only way you can get anything other than sables when breeding a sable to
a sable is when BOTH parents are *not* homozygous for sable.
If one parent is homozygous for sable, it doesn't matter if the other sable
parent is homozygous or not - ALL the pups will be sable.
Now here's something that can get confusing - proving a sable dog is
homozygous for sable. If you breed two sable dogs and all the pups are
sable, this does *not* prove that either parent is homozygous for sable.
Nor does breeding a sable to a non-sable and getting all sable pups prove a
dog is homozygous.
Same thing goes for proving a dog carries the black gene... If you breed a
dog you suspect carries the black gene to a solid black and a black pup is
produced, the dog does indeed carry the black gene. However, if there are
no black pups, this doesn't prove the dog is not black factored. It could
mean the black gene just wasn't expressed in that particular litter.
The thing to remember about genetics is that the "rules" of inheritance are
governed by statistical probabilities. Nothing more. For example...
Although a woman has a 50% chance of conceiving a girl, my brother-in-law
and his wife had 11 boys, no girls. And my mother-in-law had 7 boys, no
girls. (They were all red-headed too! )

What would one get from a sable to sable breeding, other than a true
sable?

AND
When I bred a sable JJ daughter (JJ was black) to my inbred Jeenellyn
dog, Landsend's Obie of Jeenellyn, I got ALL solid blacks (3). (The
joke was that I couldn't wait to see my first sable pup born at
Landsend--didn't happen that time!) Now, the second time I made the
same breeding I got 5 sables and 3 solid blacks. It all evens out in
the end.
