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

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 ...

Population genetics and phylogenomic insights into the origin of economically important black pepper (Piper nigrum). [PDF]
Abstract Premise We conducted population genetic and phylogenomic analyses of several cultivated Piper nigrum varieties and closely related species. We sought to establish (1) the genetic constitution of P. nigrum and its putative status as an allotetraploid hybrid of Indian origin, and (2) its relationships to other species of Piper in South and ...

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

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 ...

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.

Pedigree analysis in the mhorr gazelle (Nanger dama mhorr): Genetic variability evolution of the captive population [PDF]
Breeding programs have an essential role in the recovery of threatened populations through optimal genetic management and mating strategies. The dama gazelle (Nanger dama) is a North African ungulate listed as critically endangered.

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 ...

Small-sized animal populations can undergo significant loss of genetic variability that can lead to their extinction. Therefore, studies on animal breeding have focused on mating systems for minimizing the disappearance of genetic variability.

Genome-wide estimates of coancestry and inbreeding in a closed herd of ancient Iberian pigs. [PDF]
Maintaining genetic variation and controlling the increase in inbreeding are crucial requirements in animal conservation programs. The most widely accepted strategy for achieving these objectives is to maximize the effective population size by minimizing
