The majority of men (total n= 218,282) showed median normalized intensities for the ePAR-relevant SNPs consistent with them being present in single copy, as indicated by the pair of horizontal solid black lines (95% CI for haploid X). By contrast, 1,676 men exhibited intensities for these X chromosome SNPs in the range expected for normal females, as indicated by the pair of horizontal solid red lines (95% CI for diploid X), suggesting that they are putative ePAR carriers. The number of men and the number of putative ePAR carriers per Y-Hg are given above the plot. Some men were also observed to have intensities for these SNPs considerably lower than expected for a haploid X chromosome (between the horizontal blue lines); these are putative carriers of the predicted reciprocal NAHR product that results in a deletion in this interval. See Figure S2 for intensity data for females.
