Genomic Prediction and Genome-Wide Association Analysis of Heat Tolerance for Milk Yield in Buffaloes Using a Reaction Norm Model. [PDF]

J Anim Breed Genet
ABSTRACT The aim of this study was to evaluate the impact of incorporating genomic information on the estimation of genetic (co)variance components and the accuracy of breeding values for milk yield under varying thermal environments, and to identify SNPs associated with genes that play significant roles in heat tolerance.

Genomic Analysis of Inbreeding Depression on Productive Traits in Rubia Galega Beef Cattle Breed

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT In autochthonous livestock breeds with small populations, such as the Rubia Galega from Galicia (Spain), mating between relatives is common and can lead to inbreeding depression. Genomic inbreeding coefficients were estimated for 4984 animals using ~63,000 SNPs to assess inbreeding depression in four key traits: age at first calving (AFC) with

Odabir i stupnjevanje nazimica koristeći BLUP

Stočarstvo : Časopis za unapređenje stočarstva, 2004
Selekcija nazimica u Republici Hrvatskoj do nedavno se provodila prema selekcijskim ekonomskim indeksima Međutim koeficijenti upotrebljavanih indeksa nisu bili procijenjeni na temelju podataka domaće populacije, već su preuzeti iz literature. U svinjogojstvu Hrvatske prelazi se na odabir nazimica temeljem procjene uzgojne vrijednosti pomoću BLUP-a. Pri

Genetic interactions contribute less than additive effects to quantitative trait variation in yeast. [PDF]

, 2015
Genetic mapping studies of quantitative traits typically focus on detecting loci that contribute additively to trait variation. Genetic interactions are often proposed as a contributing factor to trait variation, but the relative contribution of ...

Genetic Parameters of Methane Emission, Feed Efficiency, Feeding Behaviour, and Growth Traits in Beef Cattle

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT Climate change has intensified the need to reduce greenhouse gas emissions, particularly methane (CH4) from enteric fermentation. Genetic selection has emerged as a promising mitigation strategy; however, studies on Bos taurus indicus , especially Nellore cattle, remain limited.

Endogamia, fixação de alelos e limite de seleção em populações selecionadas por métodos tradicionais e associados a marcadores moleculares Inbreeding, alleles fixation and selection limit in populations under traditional or marker assisted selection methods

Revista Brasileira de Zootecnia, 2007
Objetivou-se avaliar o coeficiente de endogamia, a fixação de alelos e o limite de seleção em populações selecionadas durante 20 gerações. A seleção foi baseada nos valores genéticos preditos pelo BLUP clássico (BLUP) e pelo BLUP marcadores (BLUPM) e na ...

Controlling the Overfitting of Heritability in Genomic Selection through Cross Validation. [PDF]

, 2017
In genomic selection (GS), all the markers across the entire genome are used to conduct marker-assisted selection such that each quantitative trait locus of complex trait is in linkage disequilibrium with at least one marker.

Use of Cluster Analysis for Identifying Metafounders

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT In the metafounder approach, the relationship matrix of metafounders, Γ$$ \boldsymbol{\Gamma} $$ is used to transfer information on relationships between pedigree founders into the numerator relationship matrix A$$ \mathbf{A} $$, creating matrix AΓ$$ {\mathbf{A}}^{\boldsymbol{\Gamma}} $$.

The BLUP method in evaluation of breeding values of Russian spring wheat lines using micro- and macroelements in seeds

Вавиловский журнал генетики и селекции
Genomic selection is a technology that allows for the determination of the genetic value of varieties of agricultural plants and animal breeds, based on information about genotypes and phenotypes. The measured breeding value (BV) for varieties and breeds
