New DNA Test Could Reveal Your Pets’ Ancestry
Dr. Susan Nelson, a veterinarian at Kansas State University, said K-State's Veterinary Medical Teaching Hospital has offered the blood test "Wisdom panel MX" that can determine the breed of the dog.
"The new test uses a blood sample that looks for 'breed signatures' that are specific for more than 130 breeds recognized by the American Kennel Club, with more breeds being added as time goes on," Nelson said.
"Accuracy is estimated at 84 per cent for first generation mixes. Modern dogs have a lot of identical DNA as it is thought they have descended from the gray wolf. But scientists have identified 300 sites (called SNPs) in the DNA sequence where subtle changes can occur.
"Specific combinations of variations at these sites are known as breed signatures. The report will present the breed signatures that are present in each dog's DNA. In some cases a certain proportion of a dog's genetic material will be so mixed that no breed signature match can be made. In these dogs a mixed component will be reported along with other breeds detected,” she added.
Nelson said analyzing a dog's breed is more difficult the further back one looks.
