Identification of selective sweep and associated QTL traits in Iranian <i>Ovis aries</i> and <i>Ovis orientalis</i> populations.

ABSTRACT:

Introduction

Identifying genomic regions under selection is the most challenging issue for improving important traits in animals. Few studies have focused on identifying genomic regions under selection in sheep. The aim of this study was to identify selective sweeps and to explore the relationship between these and quantitative trait loci (QTL) in both domestic and wild sheep species using single nucleotide polymorphism markers (SNPs).

Methods

Genomic data were obtained from the NextGen project, which included genotyping 20 domestic and 14 wild sheep using the Illumina Ovine SNP50K BeadChip. The XP-EHH, iHS, and RSB methods were employed to detect signatures of positive selection.

Results

The results of the iHS method indicated 405 and 275 selective sweeps in domestic
