Genetic Signatures of Coancestry within Surnames [PDF]

open access: yesCurrent Biology, 2006
Surnames are cultural markers of shared ancestry within human populations. The Y chromosome, like many surnames, is paternally inherited, so men sharing surnames might be expected to share similar Y chromosomes as a signature of coancestry. Such a relationship could be used to connect branches of family trees, to validate population genetic studies ...

How to achieve a higher selection plateau in forest tree breeding? Fostering heterozygote × homozygote relationships in optimal contribution selection in the case study of Populus nigra

open access: yesEvolutionary 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.

Inferring Coancestry in Population Samples in the Presence of Linkage Disequilibrium [PDF]

open access: yesGenetics, 2012
Abstract In both pedigree linkage studies and in population-based association studies there has been much interest in the use of modern dense genetic marker data to infer segments of gene identity by descent (ibd) among individuals not known to be related, to increase power and resolution in localizing genes affecting complex traits.

Estimating Population-Level Coancestry Coefficients by an Admixture F Model [PDF]

open access: yesGenetics, 2012
Abstract In this article, we develop an admixture F model (AFM) for the estimation of population-level coancestry coefficients from neutral molecular markers. In contrast to the previously published F model, the AFM enables disentangling small population size and lack of migration as causes of genetic differentiation behind a given level

Mating animals by minimising the covariance between ancestral contributions generates less inbreeding without compromising genetic gain in breeding schemes with truncation selection

open access: yesAnimal, 2009
We reasoned that mating animals by minimising the covariance between ancestral contributions (MCAC mating) will generate less inbreeding and at least as much genetic gain as minimum-coancestry mating in breeding schemes where the animals are truncation ...

Advantages of using molecular coancestry in the removal of introgressed genetic material [PDF]

open access: yesGenetics Selection Evolution, 2013
When introgression of undesired exogenous genetic material occurs in a population intended to remain pure, actions are necessary to recover the original background. It has been shown that genome-wide information can replace pedigree information for different objectives and is a valuable tool in the fields of genetic conservation and breeding.

General inbreeding coefficient of maize synthetics derived from three-way line hybrids

open access: yesTerra Latinoamericana, 2019
The scarcity of pure and unrelated maize inbred lines that possess high combining ability in Mexico has led breeders wishing to form single crosses to develop double-cross or three-way line hybrids (TWLHs) instead.

Improved dairy cattle mating plans at herd level using genomic information

open access: yesAnimal, 2021
From 2012 to 2018, 223 180 Montbéliarde females were genotyped in France and the number of newly genotyped females increased at a rate of about 33% each year.

A proximal decomposition of inbreeding, coancestry and contributions

open access: yesGenetics Research, 2008
SummaryWright's (1922) coalescence probabilistic method decomposes the average coancestry or the average inbreeding of the population of interest into contributions of ancestors who are directly responsible for coancestry. These ancestors are less numerous and younger than those given by Caballero & Toro's (2000) method.

Pedigree analysis and inbreeding effects over morphological traits in Campolina horse population

open access: yesAnimal, 2018
Genetic improvement, without control of inbreeding, can go to loss of genetic variability, reducing the potential for genetic gains in the domestic populations.
