you follow the yellow
squares back..you will see a sable in the
last generation. which is colored in pink.
As it goes forward,
you will see there have been tan points
there have been tan points produced from the
sable .... the sable gene is now gone..
dog cannot produce
sable, unless he is bred to a sable and if
he is carrying for tan points.
is how easy you can
lose sable in a pedigree.
