Abstract
We describe a simple algorithm to decompose both the inbreeding and the coancestry coefficients. The decomposition is performed in pieces coming from each ancestor, including the founders and the mendelian sampling terms of non-founders. The original algorithm presented here replaces the conventional tabular method formulae with an original set of recursive formulas. We illustrate the procedure with two small examples, including the pedigree of the celebrated bull Comet. The procedure was also tested with simulated pedigrees and it succeeded in analyzing the impact of successive bottlenecks into the average coancestry of the current cohort.
