We can now evaluate the coancestry between specific relatives. Consider first the coancestry between an individual and one of its offspring, f(PO). If A and B are the parents of C, fAC is an example of a parent-offspring coancestry coefficient. From Eq. (25.5), $${f_{AC}} = \left( {1/2} \right)\left( {{f_{AA}} + {f_{AB}}} \right).$$

Tabular Calculation of Coancestry
1987If L is the offspring of J × K, and if we know the coancestries of A and B with J and K, we can calculate the coancestries of A and B with L, using the first averaging rule, Eq. (25.5). These calculations lend themselves readily to a tabular format: $$\begin{gathered} \,\,\,\,\,\,\,\,\,\,\,\,\,J\,\,\,\,\,\,\,\,\,\,\,K\,\,\,\,\,\,\,\,\,\,\,L \hfill \

Estimation of coancestry in Iberian pigs using molecular markers
Conservation Genetics, 2002Genetic markers provide a useful tool to estimate pairwise coancestry between individuals in the absence of a known pedigree. In the present work 62 pigs from two related strains of Iberian breed, Guadyerbas and Torbiscal, belonging to a conservation programme with completely known pedigrees since 1945, have been genotyped for 49 microsatellites.

AbstractThe software package coancestry implements seven relatedness estimators and three inbreeding estimators to estimate relatedness and inbreeding coefficients from multilocus genotype data. Two likelihood estimators that allow for inbred individuals and account for genotyping errors are for the first time included in this user‐friendly program for
