Artificial selection with traditional or genomic relationships: consequences in coancestry and genetic diversity [PDF]
Frontiers in Genetics, 2015 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

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

Frontiers in Genetics, 2020 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 ...

A note on the rationale for estimating genealogical coancestry from molecular markers [PDF]
Genetics Selection Evolution, 2011 Background Genetic relatedness or similarity between individuals is a key concept in population, quantitative and conservation genetics. When the pedigree of a population is available and assuming a founder population from which the genealogical records ...

Fast and accurate joint inference of coancestry parameters for populations and/or individuals. [PDF]
PLoS Genetics, 2023 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.

Navigating population-level coancestry in forensic mixture analysis
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

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.

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.

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.
