Description of the CNVRs detected by a whole-genome CGH array. The genomic coordinates were expressed in bp and were relative to the Sus scrofa genome sequence assembly (Sscrofa9.2). BLAST was used to query the CNVRs sequences against the Sus scrofa genome sequence (Sscrofa9.2). Sequences were retained as duplicated sequences if they had ≥ 1 kb and ≥ 90% identity and occur at more than one site within the genome. WD: White Duroc (♀); YX: Yangxin (♂); EH: Erhualian (♀); TC: Tongcheng (♀); LW: Large White (♀); PT: Pietrain (♂); LD1: Landrace × DIV pig 1 (♂); LD2: Landrace × DIV pig 2 (♀); DIV1: Chinese new pig line DIV 1 (♀); DIV2: Chinese new pig line DIV 2 (♀); L1: Landrace 1 (♂); L2: Landrace 2 (♂).
