Intra-chromosomal estimates of inbreeding and coancestry in the Spanish Holstein cattle population [PDF]
Livestock Science, 2016 In recent years, inbreeding and coancestry are being estimated from genome-wide molecular information using a large number of SNPs. Molecular inbreeding and coancestry can be calculated for the whole genome or for particular regions of the genome.

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.

On the principle underlying the tabular method to compute coancestry
Theoretical and Applied Genetics, 1991The 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.

Changes in Allele Frequencies When Different Genomic Coancestry Matrices Are Used for Maintaining Genetic Diversity [PDF]
Genes, 2021 : A main objective in conservation programs is to maintain genetic variability. This can be achieved using the Optimal Contributions (OC) method that optimize the contributions of candidates to the next generation by minimizing the global coancestry ...

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 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.

Segment-based coancestry, additive relationship and genetic variance within and between the Norwegian and the Swedish Fjord horse populations [PDF]
Acta Agriculturae Scandinavica - Section A: Animal Science, 2020 The Fjord horse originates from Norway but forms a global population due to several small populations in foreign countries. There exists no information about the additive relationship and the genetic variance between these subpopulations.

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 ...
