Accuracy of genotype imputation in Nelore cattle [PDF]

Genetics Selection Evolution, 2014
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 genomic predictions. Imputation methods rely partially on linkage disequilibrium between markers to infer unobserved genotypes.
