Imputation of non-genotyped parents using genotype information of their relatives

In genomic evaluation, animals with reliable proofs are usually used in the training population. Even though historical proofs are normally publicly available, genotypes may not be in some circumstances. Imputing non-genotyped parents using information of their relatives can increase information content in the training population especially for countries that do not have access to genotypes of older animals. Therefore, the objectives of this study were to compare the imputation accuracy of non-genotyped parentsfrom using genotype information of different relatives and to assess the accuracy of genomic prediction using imputed parents.
