Dogs that are EE or Ee can produce dark (black, brown, blue, isabella) hairs, but their distribution will be dependent on the genotypes at the K and A loci. Dogs that are ee (recessive red) will not produce any dark hairs regardless of their genotype at the K, A, B, and D loci.
What does E locus mean?
The MC1R gene, also known as the extension (E) Locus, controls the production of eumelanin (black pigment) in the melanocytes. The dominant form of the MC1R gene (E) allows for normal production of eumelanin in the melanocytes.
What dog colors are dominant?
The four alleles of this gene in order of dominance are: melanistic mask (Em), grizzle (Eg), black (E) and red (e). K (dominant black) locus. This gene controls dominant black, brindle, and fawn colors. This relatively new locus includes colorations previously linked to other genes like Agouti.
What color is my dog carrier?
Genetic testing is the only way to be certain of dog coat color genetic heritage. In our offer you can find available genetic tests for dog coat color, which can be individual tests for specific locus ( A locus, B locus, D locus, E locus, EM locus, K locus) or panel, which includes testing for all loci available.
How can I tell what color my puppy is?
If you simply must know for sure what color of puppies your dogs are likely to produce, talk to your vet about DNA testing. A specific test will tell you if your light-colored parents carry the forms of the genes — also known as alleles — that will give them black or brown puppies.
What is E locus in dogs?
E Locus Testing:
The MC1R gene, or E Locus, has three possible forms: Black (E), melanistic mask (Em), and Red/Yellow (ee). The E-Allele test determines how many copies of the recessive “e” alleles a dog carries. The Em-Allele test determines how many copies of the melanistic mask allele a dog carries.
What is an example of alleles?
Different versions of a gene are called alleles. … For example, the allele for brown eyes is dominant, therefore you only need one copy of the ‘brown eye’ allele to have brown eyes (although, with two copies you will still have brown eyes).
Which genes are dominant in dogs?
There is a dominant black gene and a recessive black gene—though dominant black is by far the most common. There are are also two forms of yellow. Clear yellow/red is recessive and sable (yellow and dark banded hairs) is dominant.
Do dogs get more genes from mom or dad?
Puppies from the same litter commonly share 50% of their genes (on average.) Each litter mate randomly inherits 50% of its genes from his father and the other 50% from his mother.
Can puppies look like their grandparents?
Like humans, dogs may resemble their parents and their siblings, but also can exhibit some characteristics that even a good shake of the family tree might not explain. … It’s All In the Genes. All species have a genetic makeup, which is passed along from both mother and father.
