[HTML][HTML] Non-additive effects in genomic selection

L Varona, A Legarra, MA Toro, ZG Vitezica - Frontiers in genetics, 2018 - frontiersin.org
In the last decade, genomic selection has become a standard in the genetic evaluation of
livestock populations. However, most procedures for the implementation of genomic selection …

On the additive and dominant variance and covariance of individuals within the genomic selection scope

ZG Vitezica, L Varona, A Legarra - Genetics, 2013 - academic.oup.com
Genomic evaluation models can fit additive and dominant SNP effects. Under quantitative
genetics theory, additive or “breeding” values of individuals are generated by substitution …

Orthogonal estimates of variances for additive, dominance, and epistatic effects in populations

ZG Vitezica, A Legarra, MA Toro, L Varona - Genetics, 2017 - academic.oup.com
… Zulma G Vitezica , Zulma G Vitezica … For the allele frequency p = 0.5, the Cockerham
model is a particular case of the G2A and Vitezica models, thus …

Bias in genomic predictions for populations under selection

ZG Vitezica, I Aguilar, I Misztal, A Legarra - Genetics Research, 2011 - cambridge.org
Prediction of genetic merit or disease risk using genetic marker information is becoming a
common practice for selection of livestock and plant species. For the successful application of …

[HTML][HTML] Dominance and epistatic genetic variances for litter size in pigs using genomic models

ZG Vitezica, A Reverter, W Herring… - Genetics Selection …, 2018 - Springer
… [10] that accounts for additive and dominance effects is a particular case of the model to
analyze epistasis in Vitezica et al. [14], which in turn is an extension of the NOIA (natural …

Ancestral relationships using metafounders: finite ancestral populations and across population relationships

A Legarra, OF Christensen, ZG Vitezica, I Aguilar… - Genetics, 2015 - academic.oup.com
Recent use of genomic (marker-based) relationships shows that relationships exist within
and across base population (breeds or lines). However, current treatment of pedigree …

HLA-DRB1* 01 associated with cutaneous hypersensitivity induced by nevirapine and efavirenz

ZG Vitezica, B Milpied, C Lonjou, N Borot, TN Ledger… - Aids, 2008 - journals.lww.com
HLA typing, demographic and immunological risk factors for nevirapine and efavirenz
reactions were studied in a French cohort of HIV patients. Cases with isolated rash were …

Unknown‐parent groups in single‐step genomic evaluation

I Misztal, ZG Vitezica, A Legarra… - Journal of Animal …, 2013 - Wiley Online Library
… the bias of EBVs of genotyped animals as in Vitezica et al. (2011) or Chen et al. (2011). …
When G is scaled to match averages of A 22 , EBVs are unbiased (Vitezica et al. 2011). When G …

[HTML][HTML] Genomic evaluation by including dominance effects and inbreeding depression for purebred and crossbred performance with an application in pigs

T Xiang, OF Christensen, ZG Vitezica… - Genetics Selection …, 2016 - Springer
… This study extended the trivariate GBLUP model of Vitezica et al. [22] in order to obtain (co)…
The results show that the Vitezica model [22] is a tool that can be used for the genomic …

[HTML][HTML] Metafounders are related to F st fixation indices and reduce bias in single-step genomic evaluations

…, I Misztal, I Pocrnic, ZG Vitezica… - Genetics Selection …, 2017 - Springer
Background Metafounders are pseudo-individuals that encapsulate genetic heterozygosity
and relationships within and across base pedigree populations, ie ancestral populations. …
