Drawing inferences about the coancestry coefficient [PDF]
Theoretical Population Biology, 2009 The coancestry coefficient, also known as the population structure parameter, is of great interest in population genetics. It can be thought of as the intraclass correlation of pairs of alleles within populations and it can serve as a measure of genetic distance between populations.

The use of coancestry based on shared segments for maintaining genetic diversity
Journal of Animal Breeding and Genetics, 2016 SummaryWe have evaluated the use of genomic coancestry coefficients based on shared segments for the maintenance of genetic diversity through optimal contributions methodology for populations of three different Austrian cattle breeds. This coancestry measure has been compared with the genomic coancestry coefficient calculated on a SNP‐by‐SNP basis and ...

Estimation of effective number of breeders from molecular coancestry of single cohort sample
Evolutionary Applications, 2008 AbstractThe effective population size, Ne, is an important parameter in population genetics and conservation biology. It is, however, difficult to directly estimate Ne from demographic data in many wild species. Alternatively, the use of genetic data has received much attention in recent years.

Inbreeding, Coancestry, and Covariance between Relatives for X-Chromosomal Loci
Journal of Heredity, 1989Knowledge about the relationships between relatives for X-chromosomal loci is necessary to compute genetic variances and covariances for the genetic evaluation of individuals for economically important traits in livestock and poultry. Using a unified approach, we derived explicitly the coefficient of inbreeding for individuals and the coefficient of ...

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 ...

Marker-based estimation of the coefficient of coancestry in hybrid breeding programmes
Theoretical and Applied Genetics, 2009Molecular markers allow to estimate the pairwise relatedness between the members of a breeding pool when their selection history is no longer available or has become too complex for a classical pedigree analysis. The field of population genetics has several estimation procedures at its disposal, but when the genotyped individuals are highly selected ...

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).
