UC Davis Genetic Diversity Test


The world’s best Canine Diversity Test, from UC Davis’ renowned Veterinary Genetics Lab. Developed by dedicated veterinarians and geneticists specifically to assess genetic diversity in breeds, dogs, and matings.

Please order ONE test per dog.  DO NOT order multiple tests with identical names. When ordering for a litter, puppy names (collar color, numbers or call names) are acceptable prior to registration and can be changed later.  When ordering more than one, fill in the form, click “Add to Cart,” then change the name, gender, color and/or birth date as necessary and then add the next order to your cart. Repeat until all dogs are entered, and then go to your cart to check out. Thank you!!

Volume discount: $2 off each test when buying 2 to 5 tests, $4 off each test for over 5 tests. 

PLEASE NOTE: If you reside in Australia or the New Zealand, please be advised the UC Davis VGL is presently unable to mail you swabs. Please use WIDE interdental brushes and contact us for your PDF printout to send along with your swabs.

The Veterinary Genetics Laboratory (VGL), in collaboration with Dr. Niels C. Pedersen and staff, has developed a panel of short tandem repeat (STR) markers that will determine genetic diversity across the genome and in the Dog Leukocyte Antigen (DLA) class I and II regions. This test panel will be useful to breeders who wish to track and increase genetic diversity of their breed as a long term goal.

Short tandem repeat (STR) loci: A total of 33 STR loci from across the genome were used to gauge genetic diversity within an individual and across the breed. The alleles inherited from each parent are displayed graphically to highlight heterozygosity.

DLA haplotypes: STR loci linked to the DLA class I and II genes were used to identify genetic differences in regions regulating immune responses and self/non-self recognition. Problems with self/non-self recognition, along with non-genetic factors in the environment, are responsible for autoimmune disease.

Internal Relatedness: The IR value is a measure of genetic diversity within an individual that takes into consideration both heterozygosity of alleles at each STR loci and their relative frequency in the population.
