Prediction of the reliability of genomic breeding values for crossbred performance
Springer Science and Business Media LLC - Tập 49 - Trang 1-19 - 2017
Jérémie Vandenplas, Jack J. Windig, Mario P. L. Calus
In crossbreeding programs, various genomic prediction models have been proposed for using phenotypic records of crossbred animals to increase the selection response for crossbred performance in purebred animals. A possible model is a model that assumes identical single nucleotide polymorphism (SNP) effects for the crossbred performance trait across breeds (ASGM). Another model is a genomic model t...... hiện toàn bộ
Marker assisted selection for the improvement of two antagonistic traits under mixed inheritance
Springer Science and Business Media LLC - Tập 33 - Trang 1-22 - 2001
Etienne Verrier
A Monte Carlo simulation was used to investigate the potential of Marker Assisted Selection (MAS) in a multiple-trait situation. Only additive effects were considered. The base population was assumed to be in linkage equilibrium and, next, the population was managed over 15 discrete generations, 10 males and 50 females were chosen out of the 100 candidates of each sex. Performance for two traits w...... hiện toàn bộ

Fatness QTL on chicken chromosome 5 and interaction with sex
Springer Science and Business Media LLC - Tập 38 - Trang 1-16 - 2006
Behnam Abasht, Frédérique Pitel, Sandrine Lagarrigue, Elisabeth Le Bihan-Duval, Pascale Le Roy, Olivier Demeure, Florence Vignoles, Jean Simon, Larry Cogburn, Sammy Aggrey, Alain Vignal, Madeleine Douaire
Quantitative trait loci (QTL) affecting fatness in male chickens were previously identified on chromosome 5 (GGA5) in a three-generation design derived from two experimental chicken lines divergently selected for abdominal fat weight. A new design, established from the same pure lines, produced 407 F2 progenies (males and females) from 4 F1-sire families. Body weight and abdominal fat were measure...... hiện toàn bộ
Exploring the potential of incremental feature selection to improve genomic prediction accuracy
Springer Science and Business Media LLC - Tập 55 - Trang 1-10 - 2023
Felix Heinrich, Thomas Martin Lange, Magdalena Kircher, Faisal Ramzan, Armin Otto Schmitt, Mehmet Gültas
The ever-increasing availability of high-density genomic markers in the form of single nucleotide polymorphisms (SNPs) enables genomic prediction, i.e. the inference of phenotypes based solely on genomic data, in the field of animal and plant breeding, where it has become an important tool. However, given the limited number of individuals, the abundance of variables (SNPs) can reduce the accuracy ...... hiện toàn bộ
Extending long-range phasing and haplotype library imputation methods to impute genotypes on sex chromosomes
Springer Science and Business Media LLC - Tập 45 - Trang 1-4 - 2013
John M Hickey, Andreas Kranis
AlphaImpute is a flexible and accurate genotype imputation tool that was originally designed for the imputation of genotypes on autosomal chromosomes. In some species, sex chromosomes comprise a large portion of the genome. For example, chromosome Z represents approximately 8% of the chicken genome and therefore is likely to be important in determining genetic variation in a population. When breed...... hiện toàn bộ

General recommendations for the documentation of changes in dairy cattle populations and for estimating the expected genetic merit of bulls of various origin when used on specific cowpopulations
Springer Science and Business Media LLC - Tập 14 Số 4 - Trang 581 - 1982

The genetics of gaits in Icelandic horses goes beyond DMRT3, with RELN and STAU2 identified as two new candidate genes
Springer Science and Business Media LLC - Tập 55 - Trang 1-16 - 2023
Heiðrún Sigurðardóttir, Henrik Boije, Elsa Albertsdóttir, Thorvaldur Kristjansson, Marie Rhodin, Gabriella Lindgren, Susanne Eriksson
In domesticated animals, many important traits are complex and regulated by a large number of genes, genetic interactions, and environmental influences. The ability of Icelandic horses to perform the gait ‘pace’ is largely influenced by a single mutation in the DMRT3 gene, but genetic modifiers likely exist. The aim of this study was to identify novel genetic factors that influence pacing ability ...... hiện toàn bộ
