Genome-wide distribution of CPA. In each subfigure, the horizontal axis denotes the physical position of the SNP (scale in megabases, Mb) and the vertical axis denotes the estimated CPA in log₂ scale. The three red lines stand for log₂(CPA) = -1, log₂(CPA) = 0, and log₂ (CPA) = 1 with respect to the first allele being suppressed twofold compared with the second allele, no relative suppression/amplification, and the first allele being amplified twofold compared with the second allele.
