Coefficients of Kinship, Relationship and Inbreeding 8 Generations -
This page shows the inbreeding calculations for the dog you selected or the "Test Mating" you have entered. The calculations on this page are accurate to the point that they can only be made based upon the information in the database. For more detailed calculations please make sure that as many ancestors as possible are entered to the database.
More information and FAQS about COI calculation is available at the excellent site of The Institute of Canine Biology.
COI Calculation -
Sire and Dam
Ancestor-Loss coefficient (ALC)
This method doesn't replace the calculation of the COI but also gives important information for the breeder.
Ancestor-Loss is given when the same ancestor appears more than once in the pedigree of the dog. A 5-generations-pedigree shows 62 possible ancestors.
If one of this 62 possible ancestors appears twice, the dog in question has indeed only 61 different ancestors. If 3 ancestors appear twice,
this dog has indeed only 59 different ancestors. The ALC is calculated out of the nr. of the ancestors and the total nr. of possible ancestors.
