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 ...

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.

Conspecific Scaffold-Level Genome Assembly Outperforms Heterospecific Chromosome-Level Assemblies for Assessing Genetic Indicators in a Threatened Marine Fish. [PDF]

Evol Appl
ABSTRACT Understanding the genomic architecture of species of conservation concern is essential for fostering effective conservation initiatives. Current biodiversity assessment approaches increasingly incorporate genetic metrics to evaluate the status of species and populations of conservation interest.

Population genetics and phylogenomic insights into the origin of economically important black pepper (Piper nigrum). [PDF]

Am J Bot
Abstract Premise We conducted population genetic and phylogenomic analyses of several cultivated Piper nigrum varieties and closely related species. We sought to establish (1) the genetic constitution of P. nigrum and its putative status as an allotetraploid hybrid of Indian origin, and (2) its relationships to other species of Piper in South and ...

Process of Introduction of Australian Braford Cattle to South America: Configuration of Population Structure and Genetic Diversity Evolution

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 ...

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

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.

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

Genetics, 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]

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
