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 ...

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.

Genetic Signatures of Coancestry within Surnames [PDF]
Current 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]
Theoretical 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.

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

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.

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

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

Applying SNP-Derived Molecular Coancestry Estimates to Captive Breeding Programs [PDF]
Journal of Heredity, 2016 Captive breeding programs for wildlife species typically rely on pedigrees to inform genetic management. Although pedigree-based breeding strategies are quite effective at retaining long-term genetic variation, management of zoo-based breeding programs continues to be hampered when pedigrees are poorly known. The objective of this study was to evaluate
