coefficient of inbreeding

The database can also calculate for breeders the coefficient of inbreeding (COI) that two selected dogs will produce.

The coefficient of inbreeding is calculated for a single individual, and is a measure for the amount of pedigree collapse within that individual's genealogy.

Therefore, the coefficient of inbreeding is a statistical value derived from the individual's pedigree and cannot be verified or "measured" exactly by looking at the individual's genome.

The coefficient of correlation as defined by Wright (1922) is derived from the definition of the coefficient of inbreeding f as defined in Wright (1921).

For example because the entire Amish population is descended from only a few hundred 18th century German-Swiss settlers, the average coefficient of inbreeding between two random Amish is higher than between two non-Amish second cousins.
