Coefficient of in breeding of Arabian desert dogs

The mean coefficient of inbreeding (COI) of the 47 dogs tested was 6.255. An inbreeding coefficient of 0 indicates a dog that comes from two unrelated parents; 6.25 is equivalent to mating of first cousins; 12.5 equates to the genetic equivalent of a dog produced from a grandfather to granddaughter mating; 25 would equate to the genetic equivalent of a dog produced from a father to daughter mating.

COI	0	1	2	3	4	5	6	7	9	10	12	14	17	23	24	29	30
Dogs	3	9	4	6	10	1	2	1	1	2	1	1	2	1	1	1	1

Although some inbreeding is probably inevitable this does not show that it is common and in fact is less than in many pedigree dogs.

Wolfiness as measured by Embark:

Embark explains this as:

Your dog’s Wolfiness Score is not a measure of recent dog-wolf hybridization and does not necessarily indicate that your dog has some recent wolf ancestors. (If your dog has recent wolf ancestors, you will see that in the breed mix report.) Instead, the Wolfiness Score is based on the number of ancient genetic variants your dog has in our unique Wolfiness marker panel. Wolfiness scores up to 10% are almost always due to ancient wolf genes that survived many generations, rather than any recent wolf ancestors. These ancient genes may be a few thousand years old, or may even date back to the original domestication event 15,000 years ago. They are bits of a wild past that survive in your dog!

Your dog’s Wolfiness Score is based on hundreds of markers across the genome where dogs (or almost all of them) are the same, but wolves tend to be different. These markers are thought to be related to "domestication gene sweeps" where early dogs were selected for some trait. Scientists have known about “domestication gene sweeps” for years, but do not yet know why each sweep occurred. By finding rare dogs carrying an ancient variant at a certain marker, we can make associations with behavior, size, metabolism, and development that likely caused these unique signatures of “doggyness” in the genome.

Most dogs have wolfiness scores of 1% or less. We find populations and breeds with higher scores of 2-4% occasionally, and unique dogs with scores of 5% or above more rarely.

Our results:

Mean:  2.83; Low 0.6; High 11.7.

3 were less than 1% (2% of the total); 35 of the rest were less than 4% (72.9% of the total);  6 were above 5% (12.5% of the total).
