Domestication and selection are processes that conserve the pattern of genetic diversities between and within populations. Identification of genomic regions that are targets of selection for phenotypic traits is one of the main aims of research in animal genetics. An approach for identifying divergently selected regions of the genome is to compare FST values among loci to estimate the genetic v...

Implementation of genomic selection in sheep breeding provides a number of challenges, compared to dairy cattle, because of the higher genetic diversity between and within sheep breeds, the cost of maintaining reference populations and the limited ability of individual breeders to invest in genotyping. Within this study, we compare theoretical and realized genomic prediction accuracies for trai...

One of the most important issues in genomic selection is using a decent method for estimating marker effects and genomic evaluation. Recently, machine learning algorithms which are members of non-parametric and non-linear methods have been extended to genomic evaluation. One of these methods is Random Forest (RF) on which this research was focused. Important parameters in RF algorithm are the n...

    Imputation as a method of creating low-density chips to high-density chips has been introduced to increase the accuracy of genomic selection in animals. In the current study, to investing imputation accuracy, three populations of mixed (scenario 1), pure (scenario 2) and mixed + pure (scenario 3) were simulated using QMSim. Two methods of imputation including Beagle and Flmpute were used fo...
