aLocus
a/a Dog has two copies of the gene responsible for recessive black coat color.
n/a Dog has one copy of the gene responsible for recessive black coat color.
n/n Dog does not carry the gene responsible for recessive black coat color.
Blocus
b/b Dog has two copies of the brown/chocolate gene. All black pigment will be modified to brown/chocolate pigmentation.
B/B Dog does not carry the brown allele, and can never pass on the gene for brown to future offspring.
B/b Dog carries a copy of the allele responsible for brown color, and can potentially pass on that allele to future offspring.
DLocus
d/d Dog is homozygous for the dilution gene. The dog will always pass on a copy of the dilution gene to any offspring.
D/D Dog is negative for the dilution gene.
D/d Dog carries the dilution gene, but will appear full color.
Elocus
e/e The dog is yellow-based, and will always pass on a copy of the yellow allele to any offspring.
E/E Dog does not carry the gene responsible for yellow coat color. This dog will never pass on the allele for yellow coat color.
E/e Dog carries the allele responsible for the yellow coat color, and could pass on either allele to any offspring..
E/eW Dog carries one copy of the recessive white allele that restricts production of black pigment. The dog can produce black pigment, but can pass on the mutation to any offspring.
e/eW Dog carries one copy of the recessive yellow allele and one copy of the recessive white allele, and can pass either allele on to any offspring.
eW/eW Dog carries two copies of the recessive white allele, and will always pass on a copy of this allele to any offspring.
n/n Dog does not carry.
EMLocus
allele for melanistic mask.
EM/EM Dog has two copies of allele for melanistic mask.
n/EM Dog has one copy of the allele for melanistic mask.
KB/KB Dog has two copies of the dominant black
Klocus
gene, and will be self-colored. Dog will always have self-colored offspring.
n/KB Dog has one copy of the dominant black gene. Dog is self-colored, and can pass on that gene to any offspring.
n/n Dog does not have the dominant black gene, and the color pattern is determined by the Agouti gene.
Slocus
N/N Negative: Dog is negative for the spotting or parti-color gene.
S/S Dog has two copies of the spotting or parti-color gene, and will always pass on one copy to all offspring.
N/S Dog carries one copy of the spotting or parti-color gene, and can pass it on to any offspring.
M-Locus Merle (Merle / Cryptic Merle)
M/M Double Merle Dog carries two copies of the dominant "M" allele. The dog is considered an affected, "double Merle" because M/M dogs can be affected by deafness and ocular defects. M/M dogs will always pass on a copy of Merle to their offspring.
M/m Merle Dog has one copy of the "M" Merle allele and one negative "m" copy of Merle allele. The dog can pass either allele on to any offspring.
m/m Negative Dog has two copies of the recessive "m" allele and is negative for Merle. The dog will always pass on a negative copy of the Merle allele to all offspring.
CR/CR Double Cryptic Dog carries two copies of the Cryptic "CR" allele.
m/CR Merle Dog has one copy of the Cryptic "CR" allele and one negative "m" copy of Merle allele. The dog can pass either allele on to any offspring.
m/m Negative Dog is negative for Cryptic "C" allele. The dog will always pass on a negative copy of the Merle allele to all offspring.
M/CR Merle/Cryptic Dog carries one copy of the dominant "M" allele and one Cryptic Merle allele. The dog is considered a Merle, and caries Cryptic Merle. The dog can pass either allele on to any offspring.
