  1. gene: Z-linked gene in zebra finch for which orthology was inferred with crow: locus: specific location of the primers used for qPCR as inferred from orthology with zebra finch; mean m:f: male-to-female ratio in copy number averaged over all primer pairs tested for a given gene; f, m: average copy number relative to an autosomal control for a sample of four females and four males, respectively. Under the assumption of equal amplification efficiency the expected values are 0.5 for females (ZW/AA) and 1 for males (ZZ/AA). m:f: male-to-female ratio in copy number (expected to be 2 for Z-linked genes). t, p-value: t-statistic and type I error (6 d.f.) for the comparison of relative copy numbers between males (m) and females (f). Primer sequences for all loci can be found in Additional file 1 (Table 1).
