WebNov 10, 2006 · Calculation of an inbreeding coefficient involves several steps: Step 1: Generate an arrow pedigree. Step 2: List all paths that connect the sire and dam. Step 3: Locate the common ancestor in each path. The common ancestor is the individual with the arrows pointing away from it. It is the ancestor that is in the pedigrees of both parents.
