Coancestry superposed on admixed populations yields measures of relatedness at individual-level resolution. [PDF]
PLoS Computational BiologyThe 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 ...

An allele-sharing, moment-based estimator of global, population-specific and population-pair FST under a general model of population structure. [PDF]
PLoS Genetics, 2023 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 ...

Navigating population-level coancestry in forensic mixture analysis [PDF]
Scientific ReportsThe 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

Analysis of population structure and genetic diversity in low-variance Saimaa ringed seals using low-coverage whole-genome sequence data [PDF]
STAR Protocols, 2023 Summary: This protocol demonstrates how a fragmented reference genome and low-coverage sequencing data can be efficiently utilized for population genetic analyses of a species with highly reduced genetic diversity.

Pedigree analysis in the mhorr gazelle (Nanger dama mhorr): Genetic variability evolution of the captive population [PDF]
Ecology and EvolutionBreeding 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.

Animals, 2021 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]
PLoS ONE, 2013 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
