We often hear from people who suspected Ridgeback ancestry in their dog, but do not see Ridgeback represented in their dog’s results. Dogs with a fawn sable coat color and black masking (both inherited in a dominant fashion) and a larger body size often end up looking a lot like Ridgebacks, despite having no ancestry from this breed. Even one of our own team members believed that her dog, Sunny, was a Ridgeback mix before testing. You can see his results here: Sunny’s Embark Dog DNA Results.
It might also be helpful to note that a canonical ridge (observed in Rhodesian Ridgebacks, Thai Ridgebacks, and Phu Quoc Ridgebacks) is caused by a dominant mutation, meaning that a dog only needs one copy of the variant to potentially express this ridge. In fact, it's possible that a dog may have very distant ancestry from a ridgeback breed, but at a level that is below the detection threshold of our algorithms. Despite their ridgeback ancestor being too far back in their lineage for a genetic ancestry test to confidently detect, they may have inherited the mutation that causes a ridgeback phenotype to occur.
