Genetic selection strategies–population genetics

open access: yesPoultry Science, 1997
This paper provides an overview of the association between population genetics and selection strategies in poultry. Relationships between artificial and natural selection and among causes contributing to limits to artificial selection are discussed.

Runaway sexual selection without genetic correlations : social environments and flexible mate choice initiate and enhance the Fisher process [PDF]

open access: yes, 2012
Female mating preferences are often flexible, reflecting the social environment in which they are expressed. Associated indirect genetic effects (IGEs) can affect the rate and direction of evolutionary change, but sexual selection models do not capture ...

Unveiling the common loci for six body measurement traits in Chinese Wenshan cattle

open access: yesFrontiers in Genetics, 2023
Introduction: Body measurement traits are integral in cattle production, serving as pivotal criteria for breeding selection. Wenshan cattle, a local breed in China’s Yunnan province, exhibit remarkable genetic diversity. However, the molecular mechanisms

Genetic Selection and Conservation of Genetic Diversity* [PDF]

open access: yesReproduction in Domestic Animals, 2012
ContentsFor 100s of years, livestock producers have employed various types of selection to alter livestock populations. Current selection strategies are little different, except our technologies for selection have become more powerful. Genetic resources at the breed level have been in and out of favour over time.

Cupuaçu tree genotype selection for an agroforestry system environment in the Amazon [PDF]

open access: yesPesquisa Agropecuária Brasileira, 2021
: The objective of this work was to select cupuaçu (Theobroma grandiflorum) tree progenies and individuals based on their agronomic traits, and, indirectly, to identify those adapted to an agroforestry system (AFS) environment in the Brazilian Amazon ...

Multilayer perceptron applied to genotypes classification in diallel studies

open access: yesScientia Agricola, 2021
: In the last decades, a new trend to use more refined analytical procedures, such as artificial neural networks (ANN), has emerged to be most accurate, efficient, and extensively applied for mining and data prediction in different contexts, including ...

Evaluation of a new additive-dominance genomic model and implications for quantitative genetics and genomic selection

open access: yesScientia Agricola, 2021
: The Fisher’s infinitesimal model is traditionally used in quantitative genetics and genomic selection, and it attributes most genetic variance to additive variance.

Prediction of genetic gain from quadratic optimisation with constrained rates of inbreeding [PDF]

open access: yes, 2006
There are selection methods available that allow the optimisation of genetic contributions of selection candidates for maximising the rate of genetic gain while restricting the rate of inbreeding. These methods imply selection on quadratic indices as the

A lexicographic multi-objective genetic algorithm for multi-label correlation-based feature selection [PDF]

open access: yes, 2015
This paper proposes a new Lexicographic multi-objective Genetic Algorithm for Multi-Label Correlation-based Feature Selection (LexGA-ML-CFS), which is an extension of the previous single-objective Genetic Algorithm for Multi-label Correlation-based ...

Genetic analysis of environmental variation [PDF]

open access: yes, 2010
Environmental variation (V-E) in a quantitative trait - variation in phenotype that cannot be explained by genetic variation or identifiable genetic differences - can be regarded as being under some degree of genetic control. Such variation may be either
