Inbreeding coefficient table
WebBoth the inbreeding and the coancestry coefficients can be defined for specific individuals or as average population values. They can be computed from genealogies or estimated from the population size and its breeding properties, but all methods assume no selection and are limited to neutral alleles. WebThe calculation of an inbreeding coefficient involves several steps which need to be followed carefully. Figure 1. Steps 1-3. Step 1:Generate an arrow pedigree. Step 2:List all paths that connect the sire and the dam. Step 3:Locate the common ancestor in each path. The common ancestor is that individual that the arrows point away from.
