Drawing inferences about the coancestry coefficient [PDF]

open access: yesTheoretical 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.

On the principle underlying the tabular method to compute coancestry

Theoretical and Applied Genetics, 1991
The tabular method to compute coancestry between two individuals is based on the principle that coancestry may be computed as the average coancestry between one individual and the parents of the other, on the condition that the former individual is not a direct descendent of the latter.

The use of coancestry based on shared segments for maintaining genetic diversity

open access: yesJournal 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 ...

Inbreeding, effective population size, and coancestry in the Latxa dairy sheep breed [PDF]

open access: yesJournal of Dairy Science, 2020
Traditionally, breeding programs have estimated and managed inbreeding based on pedigree information. The availability of genomic marker panels has made possible new alternatives to achieve more precise estimates, for example in case of missing pedigree.

Fine decomposition of the inbreeding and the coancestry coefficients by using the tabular method

open access: yesConservation Genetics, 2010
In 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 ...

Inbreeding, Coancestry, and Covariance between Relatives for X-Chromosomal Loci

Journal of Heredity, 1989
Knowledge 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 ...
