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

Genome-wide estimates of coancestry, inbreeding and effective population size in the Spanish Holstein population. [PDF]
PLoS ONE, 2015 Estimates of effective population size in the Holstein cattle breed have usually been low despite the large number of animals that constitute this breed.

Optimizing mating strategies to maximize genetic diversity in the mhorr gazelle (Nanger dama mhorr) ex situ breeding program [PDF]
BMC ZoologyTo minimize coancestry among the offspring by equalising parents’ contributions is currently one of the most widely used methods to maximize the genetic diversity in conservation programs of threatened species.

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

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

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 ...

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 ...

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.

Animals, 2022 This study analyzes the evolution of the population structure and genetic diversity of Braford cattle in South America from 1949 to 2019 to suggest effective strategies for breeding in the future. The percentage of bulls historically increased.

Evolutionary Applications, 2021 In breeding, optimal contribution selection (OCS) is one of the most effective strategies to balance short‐ and long‐term genetic responses, by maximizing genetic gain and minimizing global coancestry.
