A note on the rationale for estimating genealogical coancestry from molecular markers [PDF]

open access: yesGenetics 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 ...

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

open access: yesFrontiers 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

Practical implementation of optimal management strategies in conservation programmes: a mate selection method [PDF]

open access: yesAnimal Biodiversity and Conservation, 2001
The maintenance of genetic diversity is, from a genetic point of view, a key objective of conservation programmes. The selection of individuals contributing offspring and the decision of the mating scheme are the steps on which managers can control ...

The use of frozen semen to minimize inbreeding in small populations [PDF]

open access: yes, 2002
In this study, we compared the average coancestry and inbreeding levels for two genetic conservation schemes in which frozen semen from a gene bank is used to reduce the inbreeding in a live population.

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 ...

Drawing inferences about the coancestry coefficient [PDF]

open access: yesTheoretical Population Biology, 2009
The coancestry coefficient, also known as the population structure parameter, is of great interest in population genetics. It can be thought of as the intraclass correlation of pairs of alleles within populations and it can serve as a measure of genetic distance between populations.

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.

Studies on association of coefficient of coancestry with progeny performance in sugarcane

open access: yesJournal of Sugarcane Research, 2021
The utilization of superior parental lines and identification of superior families enhance the genetic gain in sugarcane. To identify the superior parental lines and superior progenies, 1889 progenies derived from twenty crosses involving genetically ...

The effect of multiple paternity on genetic diversity during and after colonisation [PDF]

open access: yes, 2012
In metapopulations, genetic variation of local populations is influenced by the genetic content of the founders, and of migrants following establishment.

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
