Genomic distribution of CNVs. Arrowheads located on the left side of the chromosome ideograms represent CNVs with higher copy number in the Holstein genome (Holstein CNV gains) while arrowheads on the right side in represent CNVs with higher copy number in the Black Angus genome (Black Angus CNV gains). Note that multiple CNVs may appear as a single arrowhead due to their proximity in the genome.
