Assessing the accuracy of imputation in the gyr breed using different SNP panels
(2021-01-01)
The aim of this study was to evaluate the accuracy of imputation in a Gyr population using two medium- density panels (Bos taurus - Bos indicus) and to test whether the inclusion of the Nellore breed increases the imputation ...
Imputation of non-genotyped individuals using genotyped progeny in Nellore, a Bos indicus cattle breed
(Elsevier B.V., 2014-08-01)
This study aimed at imputing non(un)-genotyped sires using a stepwise imputation approach that combines identity by descent (IBD) detection methods with other imputation algorithms. We also studied the effect of using ...
Imputation accuracy to whole-genome sequence in Nellore cattle
(2021-12-01)
Background: A cost-effective strategy to explore the complete DNA sequence in animals for genetic evaluation purposes is to sequence key ancestors of a population, followed by imputation mechanisms to infer marker genotypes ...
Genotype imputation in a tropical crossbred dairy cattle population
(2017-12-01)
The objective of this study was to investigate different strategies for genotype imputation in a population of crossbred Girolando (Gyr × Holstein) dairy cattle. The data set consisted of 478 Girolando, 583 Gyr, and 1,198 ...
Investigating the accuracy of imputing autosomal variants in Nellore cattle using the ARS-UCD1.2 assembly of the bovine genome
(2020-12-01)
Background: Imputation accuracy among other things depends on the size of the reference panel, the marker’s minor allele frequency (MAF), and the correct placement of single nucleotide polymorphism (SNP) on the reference ...
A new HLA imputation model for admixed samples: Testing imputation accuracy in Brazil
(Wiley-Blackwell, 2022-05-01)
Accuracy of genotype imputation and genomic predictions in a two-generation farmed Atlantic salmon population using high-density and low-density SNP panels
(2018-04-01)
The objectives of this study were: (i) to assess genotype imputation accuracy in different scenarios using genome-wide single nucleotide polymorphisms (SNP) data from a population comprising two generations of farmed ...
Accuracy of genotype imputation to whole genome sequencing level using different populations of Nile tilapia
(2022-03-30)
A cost-effective strategy to obtain ultra-dense genomic information is to sequence part of population and perform imputation from lower density genotypes to sequence level for the remaining animals. The aims of this study ...
Accuracy of genomic predictions using different imputation error rates in aquaculture breeding programs: A simulation study
(Elsevier B.V., 2019)
In breeding programs, genetic evaluations can be performed using phenotypic information from the selection candidates per se or from relatives to obtain breeding values (EBV) by the traditional method known as the Best ...
Accuracy of genotype imputation in Nelore cattle
(Biomed Central Ltd, 2014-10-10)
Background: Genotype imputation from low-density (LD) to high-density single nucleotide polymorphism (SNP) chips is an important step before applying genomic selection, since denser chips tend to provide more reliable ...
