Fine decomposition of the inbreeding and the coancestry coefficients by using the tabular method
Conservation Genetics, 2010In this paper we describe a simple algorithm to decompose both inbreeding and 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 ...

Estimation of coefficient of coancestry using molecular markers in maize
Theoretical and Applied Genetics, 1993The coefficient of coancestry (fAB) between individuals A and B is the classical measure of genetic relationship. fAB is determined from pedigree records and is the probability that random alleles at the same locus in A and B are copies of the same ancestral allele or identical by descent (ibd).

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 \

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
