Discrimination of the sex-chromosomes with respect to SNP-loading and genomic information. A Proportion of the genome plotted against 95% range of SNP-loading values for PC1. Dotted black line presents the proportions for the Z-chromosomal scaffolds, dashed grey line the values from the autosomal and full black line the values for all scaffolds pooled. B Relative scaffold depth for the female plotted against the 95% range in SNP-loadings. Open grey circles refer to autosomal scaffolds and full black dots to Z-chromosomal scaffolds. The vertical line, in both plots, represents 3 SDs above the mean. For legibility, the upper value on the y axis was set to 1.5 in panel B. Two scaffolds, one autosomal and one Z-chromosomal, had relative depth greater than 1.5 (both > 15), with a SNP loading range around 0,025 and 0,15, respectively
