Table 1 The first quartile, median, and third quartile for the genomic length, and the number of SNPs per CNV for the CNVs called from the high-density genotypes. The CNVs called from the high-density genotypes are grouped separately based on the degree of overlap of the genomic position of the CNVs called from the high and medium density genotypes. Direct overlap is where is the genomic position of both CNVs were the same, partial overlap is where the genomic positions partially overlapped, and no overlap is where the genomic positions of the CNVs did not overlap
