Color Pattern (RALY gene): Saddle Tan

In addition to other new test results for coat colors, one more test result is now available for all MyDogDNA 2015 tested dogs:

Color Pattern (RALY gene): Saddle Tan

To learn more about what this result means, read the test description below:

"RALY gene defines whether tan points or saddle tan is expressed in the dog's phenotype in breeds that express both colors. 

Recessive Black (allele a) - Latest Addition to MyDogDNA Color Tests

The MyDogDNA test panel includes now a new genetic test for coat colors: The a allele in the color locus A. The result is available to all MyDogDNA 2015 tested dogs on the "Traits" tab.

The A-locus, also known as the ASIP gene, affects the production of the pigment molecule responsible for black color. Four different alleles are known at the A locus: ay, aw, at and a allele.

Dog’s Genotype and Colors

The color of a dog’s coat depends on the combined effect of many different genetic variants. Although all genes and alleles have not yet been identified, many factors and combinations are known to have effect on the final appearance of the dog. Due to the complexity of the possible combinations, as well as the hierarchy of the factors, reading the results of genetic tests for colors is not all straightforward. In order to facilitate the interpretation of the MyDogDNA test results, we have drawn the descriptive chart presented below.
