Coancestry superposed on admixed populations yields measures of relatedness at individual-level resolution. [PDF]
The admixture model is widely applied to estimate and interpret population structure among individuals. Here we consider a "standard admixture" model that assumes the admixed populations are unrelated and also a generalized model, where the admixed ...

Artificial selection with traditional or genomic relationships: consequences in coancestry and genetic diversity [PDF]
Estimated breeding values (EBVs) are traditionally obtained from pedigree information. However, EBVs from high-density genotypes can have higher accuracy than EBVs from pedigree information. At the same time, it has been shown that EBVs from genomic data

Controlling Coancestry and Thereby Future Inbreeding by Optimum-Contribution Selection Using Alternative Genomic-Relationship Matrices [PDF]
We tested the consequences of using alternative genomic relationship matrices to predict genomic breeding values (GEBVs) and control of coancestry in optimum contribution selection, where the relationship matrix used to calculate GEBVs was not ...

An allele-sharing, moment-based estimator of global, population-specific and population-pair FST under a general model of population structure. [PDF]
Being able to properly quantify genetic differentiation is key to understanding the evolutionary potential of a species. One central parameter in this context is FST, the mean coancestry within populations relative to the mean coancestry between ...

Studies on association of coefficient of coancestry with progeny performance in sugarcane
The utilization of superior parental lines and identification of superior families enhance the genetic gain in sugarcane. To identify the superior parental lines and superior progenies, 1889 progenies derived from twenty crosses involving genetically ...

Genome-wide estimates of coancestry, inbreeding and effective population size in the Spanish Holstein population. [PDF]
Estimates of effective population size in the Holstein cattle breed have usually been low despite the large number of animals that constitute this breed.

Navigating population-level coancestry in forensic mixture analysis [PDF]
The genetic similarity of unrelated individuals of the same population can be measured through the coancestry coefficient, which quantifies the probability of a pair of alleles randomly chosen having a common ancestor. It is thus expected that the higher

The use of genomic coancestry matrices in the optimisation of contributions to maintain genetic diversity at specific regions of the genome [PDF]
BACKGROUND: Optimal contribution methods have proved to be very efficient for controlling the rates at which coancestry and inbreeding increase and therefore, for maintaining genetic diversity.

Fast and accurate joint inference of coancestry parameters for populations and/or individuals.
We introduce a fast, new algorithm for inferring from allele count data the FST parameters describing genetic distances among a set of populations and/or unrelated diploid individuals, and a tree with branch lengths corresponding to FST values.

Application of optimal contribution selection, trait distribution management, and group selection in layer chickens [PDF]
Background Optimal Contribution Selection (OCS) aims at maximizing long term response to selection by balancing short term genetic gain and inbreeding rate.
