Female to male RAD locus read depth ratio along the Z chromosome, and along an exemplary autosome of approximately similar length, for P. mannii and P. rapae. RAD loci with a balanced read depth between the sexes (ratio around 1) reflect sequences present on the two parental chromosomes in each sex. In contrast, a reduced read depth in females (ratio around 0.5) along most of the Z chromosome indicates segments hemizygous in females, hence missing on the W chromosome. The horizontal lines represent the average read depth ratio observed across the autosomes. The number of individuals is 19 and 6 per sex for P. mannii and P. rapae, and the number of RAD loci on the Z and chromosome 2 is 2,501 and 2,138 for P. mannii and 2,057 and 1,817 for P. rapae.
