Genetic Diversity is shown here in picture form of multiple dogs from a variety of breeds and mixes. For each dog at least two platforms of DNA testing of genetic diversity was used. This data helps illustrate easy to understand examples of how each DNA company differs and relates to each other when it comes to the DNA profiling of inbreeding of dogs.
Wisdom Panel and Laboklin both test a dog’s genetic Heterozygosity by evaluating the DNA. A higher score is better, like in Basketball. A lower score means more inbreeding is found in that dog.
Heterozygosity of 45% is VERY GOOD
Heterozygosity of 15% is VERY BAD
Embark DNA tests a dog’s inbreeding by looking at runs of homozygosity, called COI. A lower score is better, like in Golf. A higher score means more inbreeding is found in that dog. COI is the abbreviation for Coefficient of Inbreeding.
COI of 0-10% is VERY GOOD
COI of 35%+ is VERY BAD
VGL UC Davis test shows IR, Internal Relatedness by evaluating homozygosity. As you can see in the colored graph, the lower the score the better (in the Green portion) and the higher the score the worse (in the Red portion). Think of IR as how Golf is scored, the low score is best.
To easily remember the differences between the platforms of DNA testing of genetic diversity:
COI = Golf, the lower the score the better (winner)
IR = Golf, the lower the score the better (winner)
Heterozygosity = Basketball, the higher the score the better (winner)
Pictured are multiple dogs with at least two platform’s DNA tests for genetic diversity .
*** The owners of these dogs graciously submitted their dog’s testing results to Alicia Dawn of Red-Dawn Goldens and Cavaliers. These dog’s owners are helping the public by allowing their dog’s data help educate all of us. We are grateful to each dog’s owner for their contribution to the education of understanding inbreeding in dogs.
