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.
