Fig. 3From: Genome-wide characterization of copy number variations in the host genome in genetic resistance to Marek’s disease using next generation sequencingDistribution of CNVRs in nine chicken lines. a Length distribution of CNVRs. 1200 (72.8%) CNVR events are shorter than 200 kb. b Frequency distribution of unique and overlapped CNVRs. 495 (30.02%) CNVRs occur in only one chicken line and 90 (5.46%) CNVRs are shared in all the nine chicken linesBack to article page
