Evaluation of genetic trend in milk production of buffalo cattle in Colombia

Revista Científica, 2023
Assessing genetic trends in livestock is pivotal for comprehending how populations have evolved over time. This provides valuable insights into the direction and magnitude of genetic change, which is crucial for evaluating the outcomes of selection ...

The long-term effects of genomic selection: 1. Response to selection, additive genetic variance, and genetic architecture

Genetics Selection Evolution, 2022
Background Genomic selection has revolutionized genetic improvement in animals and plants, but little is known about its long-term effects. Here, we investigated the long-term effects of genomic selection on response to selection, genetic variance, and ...

Strategies to Assure Optimal Trade-Offs Among Competing Objectives for the Genetic Improvement of Soybean

Frontiers in Genetics, 2021
Plant breeding is a decision-making discipline based on understanding project objectives. Genetic improvement projects can have two competing objectives: maximize the rate of genetic improvement and minimize the loss of useful genetic variance.

Prediction of breeding values and selection responses with genetic heterogeneity of environmental variance [PDF]

, 2007
There is empirical evidence that genotypes differ not only in mean, but also in environmental variance of the traits they affect. Genetic heterogeneity of environmental variance may indicate genetic differences in environmental sensitivity.

Oracle selection provides insight into how far off practice is from Utopia in plant breeding

Frontiers in Plant Science, 2023
Since the introduction of genomic selection in plant breeding, high genetic gains have been realized in different plant breeding programs. Various methods based on genomic estimated breeding values (GEBVs) for selecting parental lines that maximize the ...

GENETIC SELECTION | Evaluation and Methods [PDF]

, 2002
The ultimate goal of animal selection is to create a new generation of animals that are superior to the current population. Superior is interpreted broadly to include functionality of animals, cost reduction of production, consumer perception, quality of products, and reduced environmental impact.

Marker assisted selection with optimised contributions of the candidates to selection [PDF]

, 2002
The benefits of marker assisted selection (MAS) are evaluated under realistic assumptions in schemes where the genetic contributions of the candidates to selection are optimised for maximising the rate of genetic progress while restricting the ...

Genetic selection strategies–population genetics

Poultry 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.

Genetic Selection and Conservation of Genetic Diversity* [PDF]

Reproduction 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.
