COI and AVK

COI (Coefficient Of Inbreeding):
The COI is a measurement of inbreeding; a percentage that shows the probability that both genes of a matched couple are identical. This calculation checks if any of the ancestors are related to each other. Typical values are: for brother/sister or parent/child 25%, half-brother/sister or grandfather/grandchild 12.5%, etc. The formula takes in account the distance of the ancestors. You can test your combination on the "virtual pedigree" page.The lower the result, the better. The breed-average in the UK is 9%. Ideally, the COI should be calculated over at least 10 generations with fully complete pedigrees. Please note that it is calculated in real-time, so the value only represents the information available in this database.

AVK (Ahnenverlustkoeffizient = Ancestor Lost Coefficient)
This formula works with a given number of generations and calculates the quotient of the existing ancestors and the maximum possible ancestors. This is the percentage of unique ancestors in the pedigree.
