Pedigree Analysis


Coefficients of Kinship, Relationship and Inbreeding 4 Generations - Lillebrusen's Bjarki ( Kaje)

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.

COI Calculation - Lillebrusen's Bjarki ( Kaje)

The coefficient of inbreeding was determined using Genomic Relationships. Genomic relationships are constructed by identifying the genomic sources for each animal. One half of the alleles, genomic effects, are from the male parent and the other half of alleles are from the female parent. Let g be a vector of the genomic effects for all animals, of length 2N where N is the number of animals:

The genomic relationship matrix, G, can be viewed as the average of an infinite number of gametic relationship matrices, Gi, for the ith gene.

Please do the new calculation only if you have entered new ancestors of this dog!

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.
