DOMINANT
BLACK -- "K"
A dog
that is:
"K/K" or "K/k" -- dominant black;
dominant black carrying recessive black
"K^br" -- dominant black, carrying brindle
"br^br" -- brindled
"br^k" -- brindled, carrying recessive black
"k/k" -- 'normal' (recessive black)
Brindling
is 'stripes' of eumelanin-based (can be modified by the genes at the B
and D Locus, so the color could be black, blue, chocolate or lilac)
hairs in areas that are otherwise phaeomelanin based. In order to
produce the brindle color, at least one parent MUST be a brindle.
Brindle is dominant to its absence, so only one copy is needed. If a
person has a brindle colored pup for sale and there are no brindle
colors anywhere in the pedigree, then the sire that is reported on the
registration papers --- genetically can not be the (true) sire. There is
an exception to this if the dog is "e/e" or "K", he can be a carrier of
brindle.
